With Panther being two days from release, i'm starting to wonder if I really need it. For weeks i've been really excited about the release, but now that i think about it, it's $130. right now i'm on an 800 mhz iMac with 512 mb of ram running jaguar. i really wouldn't mind a speed increase if it's significant. how big is the speed jump gonna be, and do the other new features justify the $130 price?
