whoops, I meant PANTHER or Tiger Hey, I've got a ibook 1.2 ghz w/ 1.25 gigs of ram. I'm going to be using it for school. Just some word processing, email/internet, and music. It came with panther and it has the latest updates.. Is it worth it to get Tiger for it? Will I notice a huge difference? Things are alright now, but I'm used to my MBP zipping through everything. I know it won't ever be as zippy as the MBP, but will Tiger make a huge difference?
