I've been saving for a while to get a new 13'' macbook and I think I'll get one now that they are macbook pros. I'm going to get the low-end but I want a beefier hard drive an put 4 gigs of RAM into it. (I don't see 8 gigs being a real benefit for me since I won't be editing movies or anything like that. Just want a faster system.) I know how to physically instal everything but I'm confused as to what I will do when I turn it on. Do I just turn the computer on, instal Leopard from the instal disk that came with my computer then load stuff onto it I want from my current laptop with an external drive? I'm confused. Edit; I currently have a 5 year old powerbook running tiger. Will I have any processor/OS compatibility issues?
