Watching how Apple is "merging" iOS and OSX, I wondered if they would eventually start giving iOS its own "theme" the way OSX has big cats. It would make sense, Apple wouldn't want to ship "iOS 22," it would get dull and uninteresting. So perhaps they stop at 5 or 10, and then start calling it "iOS 5, Sighthound" Or something. Dogs, birds, maybe it's not even an animal. Maybe they would choose types of trees or elements on the periodic table. Or this is half-baked, I don't really know. But it's fun to think about. Any postulations?
