The hallmark feature of the Wii U is its tablet controller, the GamePad. It promises to foster some interesting, asymmetrical gameplay innovations, but one of its best features is a bit more obvious. The GamePad's screen is a perfect gaming display, and many Wii U games can be played directly on tablet itself, no television required.
Handheld gaming is certainly nothing new, but the ability to play full-fledged console games without hogging the TV is a surprisingly delightful feature we've become addicted to. Once you try it, you may begin to wonder how you lived without it.
