Looks even worse than Lion. Gate Keeper once again making Apple forcing everyone to play more and more in their own sandpit. Oh and they're not 'Mac' computers anymore either.
Looks like my Black MacBook is officially old. *sigh* Still works great though, so I guess I don't need to upgrade.
I'm still running Snow Leopard and have been hesitant to upgrade to Lion. Not sure if I'll even want to upgrade to Mountain Lion, either.
I just upgraded to Lion a couple of weeks ago. If they bring back the way to arrange Mission Control workspaces in a grid format instead of lining them all up next to each other then I'll upgrade as soon as possible. Mission Control is the most annoying Lion 'upgrade'. Otherwise I've been quite happy with it; weirdly it even seems to run faster than SL did on my oldish early 2008 MBP.
I'm still running a PPC G5 - it's still a fast and great machine (better than some of the early Intel offerings) but I'm stuck at Leopard forever.
I upgraded to Snow Leopard after 4 years on my MBP only because software and programs were becoming more and more incompatible with the earlier OS's. I'll upgrade from SL only after this happens again. Hopefully not for another 3 or 4 years. I really don't need anything more.
