I've always regarded the Mac/OS vs PC/Windows thing as a bit of fun. Sure in my 3.5 years as a Mac owner, I've had my fair share of good-natured slanging matches with PC owners (Your machine's rubbish and mine's brilliant! No your machine's rubbish and mine's brilliant repeat ad nauseum). But much in the way that I decided long ago there's no such thing as a bad piece of music if somebody likes it, then either system is great if they work for you. So while this argument raged (rages!), all the 'Mac people' were on this side of the fence, flinging rotten fruit at the poor deluded fools over there, still using Windows, and all was (seemingly) happy. Then along comes Lion. Now I started on Leopard and moved to Snow Leopard, which wasn't really a sea-change. Things got tightened up a bit and that seemed to be that. I've never been through a major Mac OS upgrade before, so it might be that this has happened with every OS change since 1984. But Civil War seems to have broken out, with the Pro-Lion and Anti-Lion brigade drawing up battle lines. I'd always found that Mac users seemed to be friendly, helpful, easy-going sorts of people (bit of a sweeping generalisation there, but it seems to hold true), so I find it really strange to see phrases like 'you stubborn / dumb downgraders' for people going back to SL, and 'you sheep that can't see the problems', for the people that are sticking with 10.7. So maybe someone with a bit more Mac heritage can tell me: is this typical of an OS release, or is Lion more 'Love It or Hate It' than we've seen for a while?
