I've had my Wii U since launch and I have never been happier with a machine.
I have bought every console and the Wii U is really a cut above the rest. Sure, the OS could be a bit faster but everything else is just amazing. The GamePad is a genius innovation in gaming, contrary to what many believe, but it really needs to be experienced to realise this. Miiverse is also amazing, bringing sharing to a new level. I can see what Sony are going with in regards to the PS4 social features with video, but to me that kind of screws the process a little. A screenshot is simple enough.
I have five games for my Wii U: Mario, Batman, NintendoLand, Nano Assault Neo and Scribblenauts, with Lego City, NFS, Pikmin 3, Wonderful 101, Zelda, Assassin's Creed 4, Watch_Dogs and Lego Marvel all pre-ordered for this year. Plus, Pokémon Rumble U for obvious reasons.
The Wii U is really good in my eyes, and the eyes of my friends, that we're not bothering to get multiplatform games on the 360/PS3 anymore, always on the Wii U where possible.
I am very happy with my purchase and it does truly astonish me that people and developers are so negative about the console.
