There are a handful of things that bother me about the Wii U (No USB3.0, no upscaling of older content etc...) but probably the worst hardware issue I find is that apparently, the Wii U touchscreen controller is SINGLE TOUCH. Just like the DS of old, this is a single tap device, which relegates it to "pointing at shit in your inventory" duty. See, Nintendo needs to realize that by 2012 when this thing releases, everyone and their mom has been playing around with some sort of touch screen device and its probably some sort of multitouch. The big "magic" of the iPad and iPhone was being able to "pinch, zoom and rotate" when it first came out and any smartphone, tablet or touch-enabled device today has more than a single touch point. People are just going to EXPECT it, but more than that if Nintendo forgot this, its really bad design.
If they say, put 3-10 touch points as would be found on other tablets there, think about all the interactions, such as being able to "grip" an item. Even 2 touch points would enable first-generation iDevice gestures, but single touch? People are going to try to "zoom in" on something and be disappointed right from the getgo, likely forced back to using the "I'd better doubletap" like a 2005 WinCE smartphone's browser.
Nintendo isn't "stealing" from Apple, but if they were they'd be doing a horrible job of it.
