I noticed Apple is spending more time/employees developing the iPhone/iPad OS than the OS X itself. Could the OS used in the iPad be used as the new/future OS X versions? For what I saw, the performance is simply amazing. Of course, you don't have the same amount of processes running in the background, but maybe they came with a better window management? I don't agree with the app store, but it's a good way of Apple getting a stake from publishers. Maybe it's Apple's next step?
