I am deciding whether or not to buy a PowerBook G4 12" 1.5Ghz. I am wanting to use it temporarily until I am able to purchase a MacBook sometime next year. I was wondering if these models of the PowerBooks are still good. The most extensive task I will be doing is multi-track recording via FireWire with GarageBand. I plan on purchasing one with it's speculations maxed out (1.25GB RAM, 80GB Hard Drive, SuperDrive). Are there any problems with these PowerBooks? Are they capable of doing the multi-track recording? Are they terrible slow compared to the MacBooks and such? Also, since I'm getting an older model, should I go with a refurbished from www.powermax.com, www.dvwarehouse.com, www.macofalltrades.com, etc. or am I safe with getting one on eBay significantly cheaper? Oh, and if I purchase a used or a refurbished model from one of these stores, am I able to get AppleCare for it? I would appreciate any help whatsoever. Thanks!
