This recent video by Nvidia explaining the new Project Shield leaves us skeptical more than anything. The android powered console works by wirelessly connecting to your PC and letting you run applications simultaneously on both the PC and the device by using its joystick controller and its 5-inch 1280×720 resolution screen.
The games running on the device make use of the same graphic card as your PC but claim to minimize any fps drop. While the device may be impressive in how well it emulates the PC game, the purpose of doing so remains a mystery, at least to me.
Considering that the wifi could not possibly extend outside your own house why would you not simply play on your PC. The market for people who need to play video games while getting food in the kitchen or while answering the call of nature must certainly be small.
Another question that might be raised is concerning the compatibility of the device with graphic cards by other producers such as AMD.
Whatever the thinking behind the product, one good thing that can be taken from the video is how well the device can run Borderlands 2.
