Interesting, as I found the GamePad to be surprisingly light for its size (as it is quite large). The Pad takes some time to get used due due to its size and shape, but I quickly got used to it and had no problems playing Rayman Legends. It molded to my hands quite nicely. The GamePad's screen was also extremely crisp and clean. I guess I was so used to the DS and 3DS touch screens.
Really solidified my purchase even more.
By the way, Rayman Legends is gorgeous. Shocking news, I know. But it was also very fun to play as well. Can't wait for it next year. ^_^
