Although lighter and less gadget that the WiiU Gamepad, his monumental battery life (over 80 hours against 3 hours for the gamepad) make it an effective tool for the longest parts.
Choosing Nintendo ABXY on the location of buttons and the right stick, however, largely seems more questionable. The positioning of the buttons under the stick definitely brings more comfort for FPS (type Call Of ...) but I'm not that kind of customer console game (only a keyboard and mouse allow you to play properly). For other game types, this positioning is a handicap, particularly because of the widely eccentric position of the button "B" (which happens to be one of the most used in a game like Monster Hunter) making the gameplay not only less accurate but also potentially painful after a few hours.
I am today came to ask me if I was not going out the WiiMote couple + Classic Controller Pro to play my favorite game.
