You disagreed with me but I think your argument is solid and people are voting you down without much reason.
iOS not only has better touch but (due to tight restrictions on background processing APIs ) way better interactive latency than MacOS, where a rogue process can still mean trying to fire up Activity Monitor. MacOS / NeXTSTEP might have a bunch of bitrot, iOS is newer, smaller and more likely cleaner. A version of xcode that works on iOS and more laptop-like devices could be a sign up OS X being on the way out.
