After using my Dell Inspiron for 2 years, it's starting to totally fall apart on me, so I've decided to make the switch to a Mac. I've saved up enough money for a PB G4 15", but now all these rumors are pointing to a new update being released sometime really soon. The dilemma comes in 'cuz my student store is offering an awesome deal on the current 15"s (another thing indicating to me that new ones will replace them too) - G4 15" 1 GHz with SuperDrive + 3 years AppleCare plan for $2200, which i think is a crazy awesome deal. The question: Should I just go for this deal or stick it out for the new PBs, in hopes they'll come before September when the school year starts? Also, I usually use my computer for schoolwork and web browsing and listening to music (+ occassional games of WC3 ). However, I also use my laptop for taking notes in class, which means I drag it with me to class everyday. Should I be looking at a 15" or a 12" for that? Right now I have a Dell Inspiron 4000, and part of the reason I'm looking at Macs anyway is cuz they're lighter and sleeker. Realistically (and not just what Apple says), is the PB G4 15" significantly lighter than the Dell Inspiron? Thanks for the help!
