Huge fail until you add Mouse support.
Seriously you could NOT have had a better demonstration on why you NEED mouse support from that guy on stage trying to select text multiple times and failing. Standing no less, hunched over with two hands and still failing to properly select the text on the first tries. We ALL know how this is. I cringe inside when I need to use my fingers to select text on my iPhone or iPad. It is a horrible experience.
Now imagine if he had been sitting, with a 12inch iPad and its type cover. With a small BT mouse, easily selecting the text. He would have gotten a standing ovation. Heck Microsoft could have come up on stage and showed off Microsoft Word with mouse support. A lot of people would have taken notice and thought..."for what I do, I can now replace my computer".
Nope. They are looking this and thinking, ok some improvements but there is no way I am remembering all of those swipes and gestures to what I can do easily with a mouse on a computer. Too make matters worse they are probably thinking...."I still need a computer and I am NOT paying these crazy Mac prices" and another Windows PC sale is made.
