I remember when the multi-touch first came out and everybody was excited. Few years and thousands of iphones have passed and the only "revolutionary" thing we can do with it is still zoom-in and zoom-out pinching pictures.
I am quite amazed by the resistance people have when thinking about HDI: take the multitouch pad on the new mac, for instance. I love it, but why there isn't even a way to do something like middle mouse button?
