My friend wants to buy this Powerbook G4 867 with 640 MB of Ram. It's a 12 incher. He is going to get it for around 850 canadian...I was wondering if this was a good price or not for him to get it...and SHOULD he get it (since now the new macbook pros and universal apps and all)? How long will it last him? he says it's just for basic web browsing, essay writing, msn messenger, occasional use of Photoshop and the iApps (iMail, iTunes, iPhoto, etc.) thank guys.
