These 7-inch MiMo USB monitors aren’t NEW new but they are now being sold at ThinkGeek, which is new. Just a shade under $130 gets you a USB-powered 7-inch monitor with an 800×480 resolution.
The screen can be oriented up-wise or wide-wise and there’s no power cord to forget, chew through, or sever with a Ginsu. Brightness is 350cd/m2, contrast ratio is 400:1. Might make a nice side monitor for all that twatting or twooting or twitterling you kids are into these days.
