The Wii U made a splash with its personal tablet controllers. Sandwiching a 6.2-inch touchscreen in between a regular analog stick and buttons, the Wii U's GamePad is like a Nintendo DS' lower touchscreen for a home console, and even lets you play games right on its screen. It streams those games from the Wii U itself, though, meaning it's basically useless when it's out of range of the console.
