I'm looking at a G4 Powerbook Titanium 667mhz 768 ram 30 gig hd. It currently has os 9.2 on it. I'm wondering if this will be new enough to run most of what I want to do (Itunes, web browsing, basic photos stuff). Where can I get a cheap copy of OS X cheap? Will the Office 2001 it has work with OS X? And what's my best bet for geting a wireless card for this thing? The asking price is only $250, it seems to work well, the disk drive is a little noisy, but seems to work. Worth getting?
