How many times did the guy tap on the screen, and nothing happened, and he had to tap again to make it work?
Also, is there multi-touch or not? He didn't seem to show it, especially while looking at photos, and you'd think that would be a great opportunity to show it off.
So Microsoft makes their rotation animation speed a little higher, and that's all it takes for people to say "Wow, that's fast!"? Yet it took a good second or two lag to get to the radio screen, with no indication that it's doing something.
