I got my Wii U and have enjoyed it overall but I have a gripe or two about the system
1. The Wii U interface is pretty slow overall- did i mention it is S-L-O-W? Can Nintendo take the time to streamline it?
2. No option to auto power down the controller (ie watching a netflix movie) as battery life is pretty poor on the tablet (I have actually thought about making a custom LION battery cable interface for a much larger battery 4-5 hours of battery life is not a plesant thing).
