Every word in the OP is wrong though.
But yeah, uhh either WiiU or Vita, but I'll vote for WiiU because I didn't get a Vita expecting to put much time into playing it; I just wanted to play Uncharted. WiiU however was a main Nintendo console, and it never delivered. There was no 'fire' in Nintendo, games were never ambitious (except Breath of the Wild, but that was delayed so much that you can't really consider it a WiiU game anymore) and it shows.
Before that I was probably most disappointed by the Gamecube. Why am I a Nintendo fan again?
