The tone of the community is really different, too—and imo the worst thing about the transition from Linux -> OS X. And ok, it's not a fair comparison, because Linux users tend to be way more technical due in part to the OS family's barriers of entry.
Still, it's annoying when you search for how to do something in OS X and the first few threads are full of people saying "that isn't how it works!
