I have reviewed a significant number of the ultraportable computers and had assessed them in their capacity for “working on the go”. The regular 15” computers would work well if you do most of the travel by car, but I have found the 13”-14” computers as being able to come up to the job when you do a lot of travel, by offering a lightweight form while being able to type easily and benefit from an easily-viewable screen.
I have written an article about the kind of pointing device to use with your laptop, including the situations when the integrated trackpad would come in handy. For the wireless mice that the article was suggesting that we use, I had found that most wireless input devices would require a proprietary dongle transceiver that plugged in to the USB port on the computer. Here, I would prefer that we go for a Bluetooth or Wi-Fi Direct mouse especially as nearly all laptops have integrated Wi-Fi and Bluetooth and you wouldn’t need to carry or worry about losing those dongles.
As for power supply, it may be wise to check through the manufacturer’s direct-sale Website store incase they offer one of those AC/Auto/Air adaptors. These adaptors have a DC input and a cord which connects to the EmPower airline DC connector or the cigar-lighter socket in a car; alongside an AC socket for the regular power cord.
If you do visit one or two particular countries or regions regularly, you could use AC cords that have plugs that are local to those particular areas for your laptop and other gadgets that use standard AC input sockets. This can be seen as a way to “free up” travel adaptors for other gadgets like mobile-phone chargers or bathroom necessities.
If the laptop uses a user-replaceable battery, you could find that you can run longer with a spare battery. It is also worth paying attention to the optional “long-run” battery packs like what Sony offers as an option for their VAIO S and Z Series notebooks. These high-capacity battery packs clip on to or install in the computer and run as secondary batteries that provide a lot of extra run time.
Of course, there had been mention about the use of headphones or a headset for your laptop as well as use of Microsoft’s Office 365 and Office Web Apps as part of your business computing needs.
One might say that, because the article was written at an HP Website, it may favour the HP products but I would still give the competing products like the Acer and Sony products a go.
