Yeah, because you have bad taste in games
Seriously though, people that don't buy video game stuff bought the Wii. Ninty got lucky and tapped a market that no one else could reach. However, that market is now pretty much the cheap iOS and Android gaming market, or better known as the ADHD crowd that just needs a quick fix and can't stick with anything.
The problem with Wii U, other than the obvious (underpowered, small HDD, terrible online connectivity, overpriced and useless controller, etc) is that it was billed as a hard core machine, but Ninty has obviously gone back on that. They don't know where or how to market it to anyone and it clearly shows. When a AAA Mario 3D title can't even help move units, you know there is a problem.
