So I returned a Macbook Pro due to noise problems and audio problems, and after reading all the garboldygook about problem here, problem there, I've decided I'll hold off on the Intel transition. So here's the question. If I get a 12" PB Rev D, how long do you think it'd be acceptable to use before I would need to switch to Intel Macs? Would it be any longer if I bought a 17" PB Rev D? I've been looking around and I see quite a few 17" PB Rev D's for 2 thousand or less, and 12" PB Rev D's for close to 1 thousand. Just curious on thoughts. I'm a college student, soon to be graduate student (hopefully). All I really use my computer for is iTunes, Word, Web, Email, Blog, and some casual Photoshop CS2. Thoughts?
