I've a 667mzh powerbook, 512mb ram, and a lovely widescreen panel - it's in very good condition - and is running the latest release of OSX. Panel has no dead pixels, and it is superb for dvd playback. It's got a 11b airport card. Battery is good for about 4 hours, depending on power settings.
I'm tempted to offer it as a trade for a Imac G4, if anyone's interested. I'm in the UK, which will likely be an issue for some folks, but you can only try eh?
You can email me at colinmac @ ecosse dot net with any questions - I'm sure I can sort some pics of it out too.
Cheers for reading !
