I gotta say, this thing is GREAT! Good job Nintendo for actually having a decent network setup. I like seeing people chatting and drawing pictures when I turn it on, and while I'm on the main menu. Makes the console feel more connected than even ps3 or xbox. The Wii to Wii U transfer is kinda clunky, and the updates are SLOOOW, but overall I'm pretty impressed.
Also the gamepad reaches my toilet, with the door closed, with only a little hiccup maybe every couple minutes. So it goes way better than I expected. The toilet is somewhere between I would say 30-40 feet away and 2 walls separate it.
