Can anyone give me a compelling reason to upgrade to Panther from 10.2.8? The only feature that really appeals to me is threaded e-mail, and that hardly seems worth $100+. Expose also sounds interesting, but doesn't seem to be worth the price of admission. Would there be any performance gains on my slightly decrepit Quicksilver 2002 800Mhz? Going to 10.2.8 already improved system responsiveness, and a further bump would be welcome. The applications I typically use are Safari, Mail, iTunes, iPhoto, Cellulo, Neverwinter Nights and occasionally Toast. I've also set my G4 up as a wireless base station with 40-bit encryption, and share my broadband connection with my Dell laptop. Given that profile, would I really derive any benefit from Panther?
