While Apple previewed some of the new features of Lion such as Launch Pad and Mission Control, I believe that the revolutionary new features lie with the auto save features and the idea that apps resume where they left off. Have you noticed the screenshots that Apple has posted for Lion? The dock has no indicators as to which app is open. Finder always has such an indicator. I don't think this is a mistake either. This definitely has to do with the idea of apps on iOS instantly opening where they were left off in the past. Perhaps they are revolutionizing multitasking on Mac OS X. I've been reading many forums and nobody has seemed to comment on this. If this is being discussed elsewhere on this forum, direct me there and I will delete this thread.
