So no one else got a Wii U? Despite my post a few pages back, i decided to get one on a whim.. it kinda did have a price drop so that makes it ok
My impressions are mostly positive - I only got Mario and it's a great game - more challenging than NSMB2 and it looks sweet in HD. I was surprised how much joy i got out of seeing just a plain mario block rendered crisply
We tried out 'boost mode' which is where a second player uses the touch screen to place blocks throughout the level to aid or hinder the first player - my wife is absolutely terrible at it but we had a good time regardless!
The gamepad controller, well the screen is pretty low res and the feed is somewhat compressed - i've noticed a few artifacts here and there which is a shame, cause it makes things look less crisp than even a 3DS. Playing on it while watching TV is pretty awesome though, as is the TV remote functionality. I think it'll be even more impressive on a game that pushes the hardware more than Mario does. I got some decent wireless range on it in my house as well, thankfully.
The system OS is really slow between apps, very clunky and disappointing considering the hardware. I was however impressed by the web browser which appears to use some pre-loading technique, cause it loads faster than my laptop browser!
