Well, I created the Ebay ad on it
No, seriously, there is nothing wrong with the laptop at all-my reasons for selling involve getting back to a larger (15") Powerbook model as well as getting a laptop with native audio in (Yay GarageBand!). The only issue that I had with it was a funky network issue that reinstalling Panther fixed (is documented in the Networking thread, if you want more background-I had to force 100/full duplex to get on the office network). All the firewire/USB ports work fine, it burns CD's and plays DVD's just fine...
I can understand being concerned about the quality or authenticity of Apple sales on Ebay-there was a 2-week span where I "busted" 5 Powerbook related scams)-about the only thing I can do is refer to my previous sales on this board (rather than Ebay).
