I've read about three reviews for the Wii U and so far the big negative appears to be battery life. Sounds like it can be a real annoyance unless you have an outlet nearby. Kind of lame but I doubt it will be a deal-breaker for anyone. The second negative seems to be how slow the UI is. Perhaps that will be improved over time. There is also some trepidation over the online functionality, but that whole deal arrived very late and most reviewers only had a few hours with it.
Other than that, the system seems solid. Pretty much everyone agrees that the GamePad has major potential to enhance games and is really nice for controlling your television experience. As with every other system, it's going to come down to the software.









Best button placement, amirite?
