My girlfriend just got a job this summer that requires her to have a laptop, except she doesn't have one so she offered to buy my ibook g4 (which is currently having trouble) for about $400. This will leave me without a computer but when I was looking into using this money to buy a pismo to tide me over till I got the money for a MBP or new intel ibook. Would this be a good idea? If I was just planing on using it for internet, word, and maybe game or two (keeping in mind the games would be Baldur's gate 2, Icewind dale, and Diablo 2 or something like that ment for the specs of the system) would I see a noticeable (i.e. unbareable) speed drop? And for that money what upgrades should I expect? Thanks.
