I still don't understand why they use iOS on these... these are essentially the same CPUs used in their laptops, so why not just use full OS X? It's basically just a touch screen macbook at this point.
Then Apple can't sell you two devices. As long as touch is only found in iOS, you can't have an all-in-one and Apple can double-dip into your pocket. I don't like it, but I get why.
