If the WiiU had been released 3/4 years ago, it might have been a contender, but in Nintendo style, they are using old tech and pricing it as if it was new tech. HD has been around for years (before 2006?), the screen on the controller is using old(and cheap) resistive tech rather then the new smooth capacitive screen found on PSVita, Ipod Touches etc... The've mixed handheld and standard consoles to create an ugly brickpad. They might as well have made the controllers wired because you can't go anywhere without the base unit anyway.
The games that will come out for it be poor ports of the games made for the hardcore consoles. They've also created there own non-standard disc for the console, so who knows if you'll be able to read the files on your PC.
You'll be wasting your money if you go out an buy this for a game or two. Wait 5 years until the unit is only worth $100-200. Your money is better spent on a next gen console (the next xbox/ps) which will have far newer hardware, more features and better games.
From a sales perspective, Nintendo consoles are aimed at ages 6-13. I can say this because I sell far more of their consoles to that age range. The only people that seem to buy a Wii that is above 15 are people buying them for their girl friends, single parents with kids or EPIC Nintendo nerds that are always looking for the latest 200th remake of Mario. 14 and higher are normalling always PS3/Xbox sales (usually bought with COD, Assassins Creed or GT5)
The Age to Console Sales range looks something like this (going from youngest to oldest)
LeapPad Explorer > Nintendo > Xbox > PS3
