Hi, I'm a college student and I'm thinking about switching over to mac. As many of you already know, I can get a free iPod nano if i purchase a mac before 9/16. I would be buying a MBP, but I am a little bit hesitant because I am not entirely sure whether I should wait till Leopard comes out in October. What do you guys think? Buy a MBP now and get a free iPod nano and get Leopard later when it comes out? or wait until Leopard comes out and buy a MBP with Leopard installed? Thanks!
