Multimode smartphone biosensing: the transmission, reflection, and intensity spectral (TRI)-analyzer | Professor Brian Cunningham, University of Illinois

My Comments

In most situations, pathology testing has required that the samples be sent away to a central laboratory to be analysed in to something meaningful for the professionals who prescribe them. This would typically take more than a day unless the laboratory was co-located with the facility that collected the sample such as in a hospital.

But there are some steps being taken to use a common smartphone as the equivalent of a pathology lab for most of the common tests. The goal with these devices is to allow the analysis of the sample and communication of the results to the end-user with a very short lead-time.

The first one of these solutions was a portable spectrograph device developed by Columbia University that connected to a smartphone’s headphone jack and worked with a special app to identify the presence of pathogens associated with certain diseases. There was also a view to have it work with less-expensive devices that could run user-installed software like the iPod Touch or low-tier Android phones, along with the ability to work on very low power.

The second one of these solutions attaches to an existing compatible smartphone and makes use of that phone’s camera and LED “flash” light to analyse the sample. It could also be set up to work with an integrated green-light laser diode as an alternative analysis light source.

This time, the sample of blood, saliva or urine is collected in a special microfluidic cartridge which means that the same “lab” could be used for multiple tests. There is a goal with this technology to adapt most of the common pathology tests to be performed with this hand-held “path-lab” and the goal can be achieved by reprogramming the software that is the companion app for this device to suit the test.

Personally, I would see these technologies initially work with the common ailment-specific “screening” tests or various “wellness” tests like cholesterol tests. There will also be an appeal to implement them with various drug tests where there isn’t a goal to achieve forensic-level accuracy. Similarly, medicine-level tests associated with chronic-illness treatment could be evolved to this technology.

But why is the idea of purposing a smartphone or similar device as a portable pathology lab appealing?

The key driver is to obtain there-and-then results suing highly-portable cost-effective equipment.

One use case is to do one or more pathology tests on a patient as they are transported in an ambulance to hospital and have the results communicated to the emergency department before the patient arrives. This also extends to situations where there are many casualties such as on a battlefield or other disaster zone. In this case, the smartphone with the handheld “path-labs” would be able to provide better-quality information for on-site treatment teams, rather than having to transport many samples to ultra-busy laboratories who may not communicate the results in time.

The rural community will also benefit in the context of routine tests especially where the nearest capable pathology lab is a long distance away from the village or town. Here, flying-doctor services, district nurses and the like can perform the common tests at the patient’s home and pass them on to regular general-practice doctors or specialists as well as making the patient and carer known of these results. It also augments the use of mobile devices as part of telemedicine efforts that can benefit this community.

But the same situation also applies to delivering healthcare in to third-world countries, something typically facilitated by the many volunteer organisations who answer this need. Here, the volunteer organisations can use this technology for identifying disease risks or organising the right treatment in a “there-and-then” manner.

Then there is the ability to use this technology as part of at-home healthcare programs including supporting the concept of ageing-at-home. This can be about using it as part of medicine management or monitoring long-term illnesses and assessing the effect of treatments without needing to go to a doctor’s clinic or hospital.

What is being seen here is the ability for cost-effective smartphones and similar highly-mobile devices that are based on platforms that support user-installable software to be used as part of personal healthcare in any part of the world.

The Google Home becomes a VoIP landline telephone

Introducing Free Calls With Your Assistant On Google Home (Blog Post)

My Comments

Using the common household phone

Could Google serve this role?

In May, Amazon launched an “over-the-top” VoIP system to allow you to call other Echo users as part of the Alexa platform. In my coverage of them launching this service, I saw it as another weapon in the battleground between the various voice-driven home assistant platforms.

Now Google have launched in to the USA and Canada a VoIP calling service which allows you to place calls to other USA or Canada phone numbers using your voice. At the moment, it is only an outgoing-call service.

As well, unless you are a Google Voice or Project Fi user, the person on the other end of the line won’t be able to see your number on their Caller-ID-capable telephone, but this will be enabled for other users to have their mobile number displayed by the end of the year. It is seen as a problem with most telephone users because robocalls and telemarketers conceal their Caller ID and users are not likely to answer calls which don’t relate to a person they know.

Here, the Google Home telephony setup works from the user’s Google Contacts phonebook which you could easily build up through your Android phone or through a Web-based user experience if you use an iPhone. There is support for multiple users with the Google Assistant differentiating them via their voiceprint.

Google still has a lot to do with making their Google Home voice-calling service catch up with Amazon Echo, such as supporting inbound calls, text and voice messaging, along with videocalls. In the case of videocalls, it may be about integrating Chromecast in to the equation, perhaps with support for a camera accessory which would be considered if they want to head towards dual-device large-screen videocalling.

But I do see Apple and Microsoft using their established VoIP platforms to make their forays to the voice-driven home assistant become communications devices.

Of course, the idea of integrating this kind of IP-telephony functionality in to Amazon Echo and Google Home platforms could be seen as retrograde by the millennial generation who are used to living without the traditional landline telephone. But such setups could be about maintaining a “catch-all” contact number for a physical location or older-generation users maintaining the idea of the traditional telephone but carrying it forward to the online era. Yet the mobile phones will simply serve as the private communications link while Google Home complements them for short calls where the privacy doesn’t matter.

Are Siri and Alexa being seen as personal companions?

My Comments

Hey Siri! Why am I alone now?

A situation that has been drawn out lately is someone feeling comfortable with their iPhone in their hand or sitting at the kitchen table beside an Amazon Echo speaker, trying to build a conversation with Siri or Alexa rather than simply asking something of these voice-driven assistants.

Is this smart speaker becoming your personal companion?

Here, a Kansas University study found that Siri, Alexa and co are being seen as a short-term panacea for social exclusion and loneliness. This is something that is being brought on by broken relationships or an increasing number of work situations where one is spending significant amounts of time away from their significant other or their normal communities. It is also symptomatic of a loss of community that has come about in this day and age.

It is also worth knowing that older and disabled adults are using Alexa or Google Home as a companion in the context of managing lights, or simply asking for the time or a music source. These devices are deliberately designed to look like other pieces of consumer-electronics or IT hardware rather than the typical bland look associated with assistive devices. They also do serve as an aide-memoire for dementia sufferers but only in early stages of this condition before it becomes worse.

But Siri, Alexa, Cortana and co are not perfect replacements for real-life friends, There is the long-term risk of you losing real human interaction if you rely on them as your companions. Here, you simply keep them serving you as a voice-operated “digital concierge” that helps with finding information or setting up your smart home rather than the be-all-and-end-all digital companion.

Multiroom to be another common feature for smart speakers

Article

Amazon Echo – to become another online multiroom audio system

Amazon Echo multiroom audio not far off, report says | CNet

My Comments

A feature that is showing up with the “smart speakers” that are part of the various voice-driven home assistant platforms is the ability for multiple speakers of the same platform to work as a multiroom system. This is where the same content source can be played through multiple speakers of that same platform, including the ability to have multiple speakers or audio devices in a logical group representing, perhaps, a floor or an area of the house. This functionality is taking on the audio-content playback abilities like Spotify, TuneIn Radio, Tidal and others offered by the various voice-driven home assistant platforms

Google Home – already a multiroom audio system as well as a smart speaker

Google has already established it with their Home speakers and Chromecast-based audio connectivity devices. But Alexa are intending to join in by allowing you to play the same content source through multiple Echo speakers and to treat a group of speakers as a logical unit. Let’s not forget that while the market’s competitive, Apple and Microsoft won’t want to miss out on the idea of multiroom audio as part of their voice-activated home assistant platforms.

Similarly, Amazon have aligned their Alexa platform with DTS’s PlayFi multiroom audio platform which is pitched at the premium hi-fi market. They have a large number of the hi-fi names with them and are wanting to integrate full Alexa voice functionality in to their speakers and other audio devices.

There may be some feature possibilities that may end up in the product evolution for these smart-speaker platforms. One of these could be to set one or more pairs of speakers up as stereo pairs which can yield the improved separation when you listen to stereo content. Similarly, there could be the idea of creating a multiple-microphone array out of a group of speakers to make it easier for the voice-driven home assistant to understand you.

Who knows how hot the competition for the voice-driven home assistant that talks to you is going to be and whether this will mimic the home videocassette format wars of the early 80s?

Mixing audio and Bluetooth Low Energy–what is happening

Article

Sony SBH-52 Bluetooth Headphone Audio Adaptor

Audio over Bluetooth Low Energy could make these devices last for a long time on a single battery charge

Apple Used Bluetooth Low Energy Audio for Cochlear Implant iPhone Accessory | MacRumors

My Comments

Any of you who have used Bluetooth headsets with your smartphones may have come across situations where the headset ceases to function or sounds the “low battery” signal when you use these devices a lot. This can happen more so if you are listening to music then make or take a long phone call using the headset and is something I had experienced many times with the Sony SBH-52 audio adaptor. But the audio protocol is being worked on to avoiding consuming too much battery runtime.

Plantronics BackBeat Pro Bluetooth noise-cancelling headphones

.. as it could with Bluetooth headsets

Apple and Cochlear, who are behind the Australian-invented Cochlear Implant hearing-assistance technology, have developed Bluetooth Low Energy Audio to provide a high-quality audio link between mobile devices and headsets but make very little demands on the battery. As well, the Bluetooth Special Interest Group are working on a similar protocol to achieve these same gains, with the goal to have it part of Bluetooth 5.0. But this has to be supported in a vendor-independent manner in the same context as the current Bluetooth audio technologies that are in circulation.

But why is there an imperative to develop a low-energy audio profile for Bluetooth?

One key usage class is to integrate Bluetooth audio functionality in to hearing aids and similar hearing-assistance devices that are expected to run for a very long time. Here, we are also talking about very small intra-aural devices that may sit in or on your ear or be integrated in a set of eyeglasses. The goal is to allow not just for audio access to your smartphone during calls or multimedia activity but even to have an audio pathway from the phone’s microphone to the hearing-assistance device as well as the phone being a control surface for that device.

Similarly, there is a usage goal to improve battery runtime for Bluetooth headsets and audio adaptors such as to avoid the situation I have described above. It can also cater towards improved intra-aural Bluetooth headset designs or lightweight designs that can, again, run for a long time.

Let’s not forget the fact that smartwatches are being given audio abilities, typically to allow for use with a voice-activated personal assistant. But devices of this ilk could be set up to serve full time as a Bluetooth headphone audio adaptor with the full hands-free operation. The expectation here as well could even be to have the display on the wearable active while in use, whether to show the time, steps taken or metadata about the call in progress or whatever you are listening to.

Once audio over Bluetooth Low Energy technology is standardised, it could be a major improvement path for Bluetooth-based audio applications.

An Internet-connected laptop could replace the link van for location broadcasting

Dell Inspiron 15 Gaming laptop

A laptop of the Dell Inspiron 15 7000 Gaming class could end up as today’s equivalent of an outside-broadcast link truck if the BBC has its way

IP Studio whitepaper

My Comments

If you watch news, sports, live concerts or similar content on TV, you will be seeing location broadcasting at work as they bring that footage to your screen.

Typically, a location broadcast that any TV studio does either required the use of video recordings that were transported to the studio before broadcast. Or they relied on a “link truck” which is a vehicle equipped with an antenna that beamed the location signal back to the studio using a microwave link if the idea is to allow the studio access to real-time vision. Some regular venues that are regular sources of content may implement a wired connection facilitated by a leased line between that venue and the studio.

Such setups have been limited by the amount of time required to locate the link truck and establish these radio links. This can also be limited through factors like weather or making sure of a line-of-sight connection to the studio’s link tower.

But the Internet and the size of computer technology has opened up the possibility of a laptop of the same or better calibre as the Dell Inspiron 15 7000 Gaming I recently reviewed connected to a high-bandwidth Internet connection as an alternative to the traditional location broadcast setup, especially for shows directly streamed to the Internet. The technology which is called IP Studio is part of an effort that Auntie Beeb is taking towards implementing IP technology for TV-show production. In this context, it is about being able to use a mobile wireless network to interconnect the cameras to the laptops for location broadcasting.

Here, they are using the Edinburgh Festival and Edinburgh Fringe Festival to prove a setup based around laptops that are uplinking to the Internet via the same kind of technology used for Internet service. The editing software that is being used is primarily a Web-app which works in the browser rather than a standalone app. But it could allow for the link-van approach where a laptop is used to upload the edited vision to the broadcaster’s studio to be inserted in to the program.

Once it is proven, the BBC’s IP Studio technology which is based primarily on open-source tools, could be seen as beneficial for all sorts of broadcasters who want to save money and set-up / tear-down time on and see increased flexibility with their location work. For example, news-gathering teams could be able to set up and “go live” on that breaking event or press conference with a very short lead-time.

The same technology could open up affordable location-broadcasting technology to community broadcasters and specific-event Webcasters who place importance on cost-effective setups. Even organisations who have video-editing talent in their staff or volunteer collection could see this technology appeal to them.

What this is showing is that the Internet and cost-effective computer design is making big-time broadcasting and production technology more affordable.

Traditional movie and TV studios shine towards direct video-on-demand services

Article

Apple TV 4th Generation press picture courtesy of Apple

Could the various smart-TV platforms like Apple TV, Chromecast or Roku be required to run “content malls”

Disney Is Dumping Netflix And Launching New Streaming Apps | FastCompany

My Comments

Traditionally, movie and TV production studios have been making their wares available through distributors or other third-party elements.

But what has happened is that they are moving towards running their own video-on-demand services in a similar way to how some manufacturers and first-party distributors have set up their own “direct” mail-order or online storefronts in the US market.

Disney is heading this way by moving their content from Netflix to their own service, something they were announcing as part of a third-quarter earnings call. It may sound close to the established “catch-up TV” model especially where the TV channels are running their own content for a long time on their video-on-demand services. Here, Disney sees this service they are exposing as the online home for some of their content like Toy Story 4 or the live-action version of the Lion King, along with putting their library of TV and movie content onto video-on-demand. Could this mean the ability to “pull up” Disney’s short cartoons that graced Saturday morning children’s TV or the early part of the cinema sessions before and after World War II. Or the ability to see those classic animated feature-length movies that

Here, it is similar to what HBO and CBS have been working on by offering a direct video-on-demand service for their content. But the “studio-direct” model could lead to difficulties in navigating content of a kind offered by multiple studios, as well as requiring potential viewers to sign up with multiple video-on-demand providers. In some cases, it may also affect whether a potential viewer signs on because of the cost of the service or the kind of business model offered by the provider. It may appeal to those of us who shine to a particular studio’s output.

Studio-direct VOD along with niche VOD may then lead to a requirement to establish video-on-demand as a “content mall” facilitated by mobile / desktop-computing platforms and smart-TV / set-top / games-console platforms. This may involve the use of content directories that link to the service providers in a similar vein to TuneIn Radio or vTuner for Internet radio. At the moment, Roku is the only provider who is working close to a “content mall” for their set-top platform, but there will be pressure on other platforms to take this approach.

It is very interesting times ahead for video-on-demand as the traditional “single-front” Netflix model falls away to the mall-based approach.

USB 3.2–coming soon to your computer

USB 3.2 to use the same USB Type-C connector as USB 3.1, but with increased throughput

USB-C is already getting a major update, and it will double data transfer speeds | Mashable

My Comments

The USB connection has been recently revised once more, but this time it is about increased bandwidth.

This standard emerges in the form of the USB 3.2 which allows for bandwidths of at least 15Gb/s thanks to the use of multi-lane technology.

It uses the same physical connection standards as USB 3.1, which means that devices equipped to this standard will use USB-C connections and you can connect your compliant host devices to your compliant peripherals using USB-C cables. But this system will work on a “best-case” approach where if both the host and peripheral device are USB 3.2 compliant, you will benefit from the higher throughput whereas in other cases, the link will step back to USB 3.1 specifications.

Once the standard is set in stone, you may find that some devices such as some computer USB interface chipsets may support in-field software-based upgrading for this standard. On the other hand, a subsequent generation of computer and peripheral equipment will end up being equipped for this standard.

The main applications I see this connection come in to its own would be high-capacity external storage applications or high-resolution display setups. But of course, there will be the USB hubs and docks (expansion modules) that are about increased connectivity being equipped with this connection type.

Personally, I would see USB 3.2 become a “next-generation” approach for USB-based peripheral and device connectivity, something to look forward with subsequent generations of computer equipment.

NVIDIA offers external graphics module support for their Quadro workstation graphics cards

NVIDIA

Press Release

My Comments

Over the last year, there has been a slow trickle of external graphics modules that “soup up” the graphics capabilities of computers like laptops, all-in-ones and highly-compact desktops by using outboard graphics processors. Typically these devices connect to the host computer using a Thunderbolt 3 connection which provides a bandwidth equivalent to the PCI Express expansion-card standard used for desktop computers.

At the moment, this approach for improving a computer system’s graphics abilities has been focused towards gaming-grade graphics cards and chipsets, which has left people who want workstation-grade graphics performance in the lurch.

But NVIDIA has answered this problem by providing a driver update for their TITAN X and Quadro workstation graphics cards. This allows Windows to work with these cards even if they are installed in a “card-cage” external graphics module rather than on the host computer’s motherboard.

Not just that, NVIDIA are to start allowing external-graphics-module manufacturers to tender their products for certification so that they are proven by NVIDIA to allow these cards to work reliably to optimum performance. This may be different to the context of a certified workstation where all the components in that particular computer are certified by Autodesk and similar software vendors to work reliably and perform at their best with their CAD or similar software.

What is being pitched in this context is a “thin-and-light” laptop of the Dell XPS 13 kind (including the 2-in-1 variant);  an “all-in-one” desktop computer like the HP Envy 34 Curved All-In-One or an ultra-compact “next unit of computing” unit like the Intel Skull Canyon being able to do workstation-class tasks with the kind of graphics card that best suits this computing requirement.

The question that some workstation users will then raise is whether the computer’s main processor and RAM are up to these tasks even though a workstation-grade graphics card is added on; and then consider this approach unsatisfactory even though the host computer has a lot of RAM and / or runs with a Core i7 CPU. But something like a gaming laptop that uses a gaming-calibre graphics chipset may benefit from the Quadro in an external graphics “card cage” module when this system is destined to do a lot of video editing, CAD or animation work.

Personally, I see the concept of the Quadro workstation graphics chipset in an external graphics module as a way to allow hobbyists and small-time professionals to slowly put their foot in the door of high-performance workstation computing.

Product Review–Dell XPS 13 2-in-1 convertible Ultrabook

Introduction

Dell has established the XPS 13 as a value-priced Ultrabook that ticks the boxes when it comes to the kind of functionality that it offers for its product class. There was some doubt that they would offer a “2-in-1” ultraportable computer under this banner alongside the traditional “clamshell” model, due to there not being an essential need for that class of computer.

Now they have offered a 2-in-1 convertible variant of the XPS 13 and it is what I am reviewing. There are two different configurations being offered for this model, one with the Intel Core i5 CPU, 8Gb RAM and 256Gb solid-state storage alongside the premium variant which comes with an Intel Core i7 CPU, 16Gb RAM and 512Gb solid-state storage.

Aesthetics and Build Quality

Tablet mode

The Dell XPS 13 2-in-1 had the same build quality as the XPS 13 clamshell where it came across as being very durable. The outside is finished in aluminium while the keyboard surround maintains that rubberised finish that provides that tactile non-slippery feel. The only disadvantage I see with this is a combination of oily hands and fine dusty materials may have it look dirty.

This convertible smoothly swivels all the way from closed to a tablet position and even closes up neatly and tightly. This again makes for something that has the smooth feel to it.

Tent mode

I paid attention to how this computer kept its cool, with respect to system performance, battery runtime and user comfort. Here, I haven’t noticed any overheating going on even after I viewed video content on this system. This is thanks to the metal housing and the way the system is architected to work in the context of an ultra-thin design.

User Interface

The illuminated keyboard has that distinct feedback that allows for accurate typing especially if you are a touch-typist. It lights up in an “on-demand” manner that avoids excessive battery drain but can be turned off. The way I have seen the keyboard light up means that the keys are more discoverable especially for those of us who are one-finger or two-finger typists.

The multi-touch trackpad works as expected and doesn’t act in a hair-trigger manner, so you don’t have to worry about disabling it if you are working on your lap. The touchscreen works as expected for a tablet screen but at times can be a bit unresponsive especially if you have your hands on the edge.

The Dell XPS 13 2-in-1 comes with a one-touch smartphone-style fingerprint reader just under the keyboard where you just put your finger in the one place for it to be recognised. This works in conjunction with the Windows 10 Hello functionality that allows for fingerprint recognition and Dell also supplied the Keeper password vault for those of us who want to keep our online service passwords on a secure digital keychain.

Here, it is the second consumer-focused computer that I have come across for review to be equipped with such a device, something typically associated with business-grade computers. What I had found from my experience was that it was reliable to scan even if you had something like the oil from deep-fried food on your fingers. But you have to scan your finger lengthways as well as pointing vertically during the Windows Hello setup procedure so it works when you are using the XPS 13 2-in-1 Ultrabook as a tablet.

Audio / Video

The Dell XPS 13 2-in-1 implements the MaxxAudio sound-tuning but I have tried it with playing music using the Spotify online music service. Here, the sound from the internal speakers is very typical of what is offered for laptops, especially the “thin-and-light” units thanks to the small chassis. This means that you don’t get the full sound reproduction when you use these speakers and it may be good enough for notification sounds or dialogue, but I would recommend using external speakers, headphones or a sound system if you want to enjoy playing music through this laptop.

The video playback behaviour for this computer has come through very smoothly especially with on-demand content and can show that you could use it for any class of video content. It would also work well for gaming environments that aren’t too demanding.

Connectivity, Storage And Expansion

Left-hand-side connections – Thunderbolt 3 over USB-C port with PowerShare and USB Power Delivery, audio input-output jack

The peripheral-connectivity options for the Dell XPS 13 2-in-1 are a pair of USB-C connectors. One of these is a Thunderbolt 3 connector that comes in handy with equipment like external graphics modules while the other is equipped with DisplayPort alt connectivity for use when you want to connect an external screen as long as  you use the appropriate adaptor or expansion module dock. Both of these ports implement the USB Power Delivery specification and also implement the PowerShare “sleep and charge” option, only enabled through the BIOS user interface rather than a Windows program.

Dell XPS 13 2-in-1 Ultrabook - USB-C power

USB-C as the power connection

The Dell XPS 13 2-in-1 has become the first computer model that I have had access to for review which implements the USB-C connections exclusively as a peripheral connection and power-input connection. It is a sign of things to come with laptops that are designed to be thin and light where this kind of connection will be the only peripheral connection type. But I am pleased that there are the two connections compared to just one of them, thus still allowing you to connect more devices at once.

Right-hand-side connections – USB-C port with DisplayPort alt video mode, USB Power Delivery and PowerShare; MicroSD card reader

There is also an audio jack as the other device connectivity option, compared to the XPS 13 which implements standard USB connections for other peripherals. Let’s not forget that the XPS 13 2-in-1 comes with a short adaptor cable that allows you to connect devices with the traditional USB Type-A connector to one of the USB-C sockets. If you are wanting more connectivity, I would consider using the Dell DA200 USB-C connector module if it is just external displays, USB peripherals and an Ethernet networks segment you want to connect or the Minix Neo C USB Multiport Adaptor if it’s your digital camera’s SD card you want to download while being able to connect external displays, Ethernet networks and other peripherals.

The secondary storage options available are adequate for most portable-computing needs. This is through the entry-level variant coming with a 256Gb SSD and the premium variant coming with the 512Gb SSD. Personally, I would like to see Dell offer a step-up variant or mid-tier option with the 512 Gb SSD as the only incremental feature over the entry-level model to court those of us who aren’t chasing the performance expectations but want something that can make it appeal as a sole-use computer.

Thanks to the slimline design goal, the Dell XPS 13 2-in-1 convertible laptop has a microSD card slot as its integrated removable-media option. This will be a limitation for those of us who use digital cameras or camcorders and want to download images to the computer by removing the SD-card “film” from the camera and inserting it in the computer. In this case, you would have to use an SD card reader that plugs in to the computer’s USB-C port with or without an adaptor.

The Wi-Fi network adaptor still works effectively even if it is on the fringe of a Wi-Fi network segment and still provides the necessary throughput.

Battery Life

The non-removable battery in the Dell XPS 13 2-in-1 convertible Ultrabook is able to satisfy general-purpose computing tasks for a day without the need for you to carry the charger with you. I even ran a TV show from SBS On Demand for an hour and found that the battery had 68% capacity left in it after that.

These results may be typical for a relatively-new machine and the battery may not last as long for a unit that has been in service for many years.

Other Usage Notes

The people in the different communities that I associate with whom I have shown this computer to are impressed with the fact that this computer answers the thin-and-light market call while also being an elegant 2-in-1 convertible. At the moment the only thing that will put them off the computer would be the price.

Limitations And Points Of Improvement

As far as the USB-C connections go, an improvement I would like to see would be to provide the same advanced connection types i.e. Thunderbolt 3 and DisplayPort alt on both ports. This may involve having the computer effectively have two Thunderbolt 3 host interfaces and two DisplayPort connections off its Intel HD integrated graphics circuitry, but could allow for simplified error-proof connectivity of display devices and Thunderbolt 3 peripherals.

In relation to the Thunderbolt 3 connection, the Dell XPS 13 2-in-1 could implement a high-power performance-focused stance while it is connected to an external graphics module that supplies the right amount of power. This would then make it able to handle advanced graphics tasks like gaming at home, but this may be limited by issues regarding heat management for a thin-and-light chassis.

A feature that would improve the Dell XPS 13 2-in-1’s useability would be to have dedicated volume buttons on the edge of the screen or as touch buttons on the bottom of the screen to allow the user to instantly regulate sound volume when playing multimedia. This would be more of importance when the computer is operating in a tablet, presentation viewer or tent mode.

Similarly, providing a standard SD card reader in a 2-in-1 Ultrabook like this may be a challenge but could be looked at especially for those of us who use these computers to download pictures or footage from our good digital cameras or camcorders

Conclusion

I would see the Dell XPS 13 2-in-1 Ultrabook as a viable option for someone who is after a “Yoga-style” convertible notebook but want something that conveys a thin, light and elegant image. The configurations that are available at least put its RAM and storage capacities above average for its peers offered by its competitors and definitely underscore value for money for its product class.
