Gestures I could care less about
However the Wifi hotspot is interesting. I assume Carriers will have policies for this that tie in with the existing tethering solution.
I would be interested to see how that impacts iPad 3G sales. I would guess most iPad users are carrying an iPhone. If you can use your iPhone as your Wifi connection then the inbuilt 3G is a little redunant.
I like the concept of making more use of AirPlay. I already love using the iPad or iPhone with AppleTV for a remote or for streaming. The idea of moving other output such as games to AirPlay is nifty.
