...took it back, and then spent the money on a PS4.
The UI was abysmal, the controller was abysmal, and the lack of account unification just drove the final nail in the coffin.
With my PS4, I can grab the controller, which has minor changes in comparison to the previous 3 generations, pick up a game, and get started.
With the WiiU it's an annoying game of;
1. Power on WiiU.
2. Pick up tablet to start actual game.
3. Grab WiiU Pro controller and play actual game.
With the PS4, it goes like this;
1. Grab controller.
2. Press power button to turn on controller and system.
3. Play game.
With the WiiU I had to touch 3 devices to play 1 game. With the PS4, just one device. Simplicity is key and king, so Nintendo needs to beat their R&D over the head with that concept. It is especially sad since Nintendo pretty much introduced the world to what is now the Sony and MS controller styles.
FWIW, I have been a gamer since the Atari 2600, so Nintendo has a place in my heart, but after the SNES, I was almost exclusively Sony.
I did buy a Gamecube at one point, but the lack of content and Mario Sunshine pretty much killed it for me.
