The Wii is a fantastic gaming system, but portable? Until now, the answer would have been a resounding No! Chinavision has just released a 7″ companion screen for the Nintendo Wii. This little bugger clips on to the back of your Wii console, and sports a folding mechanism for easy stowage once you’re grown tired of playing Mario Party on such a tiny screen. It draws power from the Wii’s power brick, though it can also be run by way of the included cigarette lighter adapter. We’re honestly not sure how pleasant the Wii’s interactive gaming would be on a 7″ screen, but if you absolutely must take your system with you on a long car ride, this is pretty much the only game in town.
