I'm going to be a new freshman at college this fall and will be purchasing an Apple laptop next week (or so). My question is, which of the following would be best for longevity, power (I use PhotoShop), and price? 14" iBook 1.2 GHz G4 512 MB RAM Bluetooth/Airport Extreme 60 GB HDD Superdrive $1714 -or- 12" PowerBook 1.33 GHz G4 512 MB RAM Bluetooth/Airport Extreme 80 GB HDD, 5400 RPM Superdrive $1802 -or- 15" PowerBook 1.5 GHz G4 (The difference in this config for the 1.5 and the 1.33 15" PowerBooks' is $100, I think $100 warrants the 1.5 GHz processor.) 512 MB RAM Bluetooth/Airport Extreme 80 GB HDD, 5400 RPM Superdrive Lighted Keyboard $2344 BTW: I will be using the computer as my primary computer and will use it for tasks ranging from email/typing papers up to PhotoShop and iMovie/iDVD work. If I had to guess, I'd estimate my usage of higher powered apps at around 1+ hours a day, FWIW. Thank you so much.
