The Wii U is actually a decent system. HD graphics, semi-competent online, decent eShop, and a Super NES style controller (just with a giant touchscreen in the middle, lol) make it usable. If you're willing to play some multiplats on it (I have ACIV, BLOPS2, Arkham City), the library isn't even that bad.
It is though a giant marketing mistake ... Nintendo should have known that going in this direction was a dead end because the PS3/360 saturated the market here.
Should've ditched the gimmick controller (or bundled it instead with Nintendo Land seperately, like Wii Fit + balance board) and just made a full on next-gen system and let the 1 year head start ride. Dump the Wii name. Called it the "New Nintendo Entertainment System". Boom.
