Hey everyone. I am stepping up from a 4yr. old powerbook G4 to this. I am going w/ the 2.16hz option and what was wondering what are the must haves or must upgrades when ordering? I am mostly getting it for everyday internet usage and for keeping track of invoices, monthly expenses etc of a business I have just started up. I am not a gamer nor will I do any video editing etc. Am I good w/ getting a "stock" machine and just upgrade later if necessary? I was thinking of doing the 2gb RAM now for $175, but that isnt "necessary" I guess. Coming from 128mb RAM, 1GB willl be insane So is there anything that I really should do now instead of later? TYIA *EDIT* Also, do these machines get hot like my powerbook does? How is the cooling system?
