A higher density screen that is only slightly better than current Android phones, a lack luster multitasking architechture, video chat that ONLY works with other iPhone 4 users... not "game changing" in my opinion.
Facetime is the one that just bugs me. What is Jobs thinking? Why would you not call it iChat and allow it to work with desktop-iChat? Even then it would still be a joke. With Qik, any Android phone, or more important any phone period has the ability to communicate with other Qik users regardless of their phone. How does he expect Facetime to take off? Apple spearheading an open video chat platform would be ... cool. I still am not sure I would jump to the word "revolutionary".
Or is it just a sale gimmick?
