Ok, So I've seen other threads about this, but not the OS Specifically, so hang with me... If I buy a Powerbook now, when the new Intel PBs come out, and OS X 10.5 (Leopard), will Apple only release OS X for the Intel Mac, or would they release 10.5 in both PPC, and Intel chipsets? That being said, would it be worth it to sink $2,300 into a new '15 PB right now? I'd like a computer for college this summer, but I don't have that type of money to spend, let alone throw away. Dammit Apple, just when things were looking clear and simple for me... Uhg. Thanks.
