I've been installing Panther on machines all day. Haven't had a chance to really enjoy it, though I've been playing between applications installs (I like to do full wipe OS installs, I just don't feel fresh and clean unless I do it that way, though man is it a pain).
Is this the official Panther Rocks thread? Why isn't there a big, holy crap Panther is here thread? Am I not seeing it?
Anyway, I'll start to express my impressions here and finish them wherever appropriate I guess.
I have two words for Panther:
1. Holy
2. Crap
Jaguar did not impress me. Panther impresses me. GUI is much improved, still a little sluggish on the outer edges, but I bet it's near glass on the G5s. The Finder finally feels old-school OS 9, with the quickflick edit modes, labels and responsiveness. Core Apple applications blast open and even the big apps launch about 30% faster for me so far. Preview is the freaking bombuber fast, absolutely crushes Acrobat. OS-level archiving of files to zipnice touch, in-line search filtering-yum (though painful on large volume searches), tons of other subtle polishing that I'd love to rave about as this or other threads grow.
If Jaguar was a B- (for me), Panther is an easy A, maybe an A+ (I'm still holding out for a FULLY multi-threaded Finder and utter glass window resize GUI).
