Yes! I've recently upgraded to OSX 10.6!
Pretty damn sweet, at first I didn't really notice any big differences.
But now, after using my mac more properly, I realize the whole thing handles like a dream, quick and snappy. Well worth the 30!
The new QuickTime, Safari and Spotlight features are pretty cuwl as well.
(Don't ask, I just felt like sharing this vital piece of information).
Will, over and out. <3
