One of the compromises frequent travelers have to make is the limited screen size that comes with an ultraportable or thin-and-light laptop. This is a difficult transition, especially if one is used to large 20-inch-plus screen real estate in the office or home. Fortunately, USB monitors provide an easy way of extending the display without bringing in a separate power supply.
Mimo's new 710-S 7-inch USB monitor ups the portability ante by coming in a clamshell form factor. This protects the screen when the unit is not in use. The 800x480-pixel resolution isn't great, but works well as a secondary monitor for instant messaging and e-mailing. The screen can be rotated to portrait mode as well. Its 350cd/m2 brightness level and 400:1 contrast ratio make it suitable for use in most indoor environments.
