I'm going for the Mac Book Pro 2.0 GHz. I'm getting everything standard, except I can't figure out if I should upgrade the hard drive speed. The upgrade is $90, and it also means I don't get instant gratification (because I can't just go pick it up at an Apple Store). So what should I do? What is improved with the speedier HD? If start up time is reduced significantly with the higher HD speed, I might go for the upgrade because I plan on using Boot Camp here and there.
