Hi! I'm in the process of buying a used notebook and need advice really fast, Monday i'm buying! I have the choice between a Powerbook 876 12" or an iBook 1Ghz 12", perhaps a 14" 933 iBook. Which one of them is the best buy, alos long term? I'm a graphic designer, and need the notebook for on the field work and presentations. I use adobe and macromedia products, no video editing or sound editing! Oh, or a Powerbook 15" 667? I'd really appreciate as many comments as possible! Oh yeah, whichever I get will have 640 MB RAM. IS IT TRUE THAT THE 876 12" Powerbook CAN ONLY HANDLE 640 MB?? OR WILL IT HANDLE MORE? Thanx!
