I am interested in purchasing a new C2D MBP. I had previously looked at the other MBP and was going to upgrade the hard drive to a 120. As well, I was going to upgrade the memory to 2GB. Now 1GB is standard and as well the 120 is standard. Well now I want to go to a 160. I know there's a 200 but I don't want to have that decrease in speed. I didn't even know 200's were available. As for the upgrades, is it cheaper for me to buy the stock unit and do the upgrades on my own or am I better off just buying from Apple and getting it with 2gb and the 160 gig hard drive? How hard is it to do these upgrades?
