Do you run Windows 8 on an existing or low-end laptop that doesn’t have integrated touchscreen abilities? If so, you may find that the experience is not all that enjoyable, even if you work the interface using the multi-touch trackpad.
Lenovo have answered this situation with a portable 15” monitor known as the LT-1423. It is available as a USB 3.0 DisplayLink variant that connects to your laptop via the USB 3.0 cable or as a Wi-Fi variant which exploits the WiDi technology. The Wi-Fi variant has its own battery and can run a continuous session for four hours but the USB version is known not to put much impact on the laptop’s battery runtime.
What can be an issue here is that you may find it hard to get used to the idea of a second screen being the main touchscreen for your laptop while you have the screen above your keyboard serving secondary duties such as a copy-entry screen. As well, you may find that some applications like hardcore real-time games may not work well with this screen as DisplayLink doesn’t implement a high refresh rate for these applications.
Even if your laptop has touchscreen abilities, this screen could work well as a “B screen” for managing a screenshow or having notes on display during that screenshow. You could even use this as the wide-work-area setup on the road when you work that extra-large spreadsheet.
This is another example of Lenovo offering methods of gaining more mileage out of existing computer equipment.
