Hi, my friend wants to buy a used powerbook and I need some advice on getting a good system for a good price. I found a deal at this website: http://www.macofalltrades.com/ Here are the specs: 15.2" Titanium Powerbook G4 500 Mhz 512MB RAM 20GB HD DVD Drive Airport Price: $900 She intends to do pretty simple things with the powerbook like internet/email, organizing digital photos, word processing, watching dvds, etc. so nothing intensive like gaming. Is this setup fast enough with OS X Panther? And is it a good price? Could you recommend another store that might give a better deal? Thanks for your help.
