A friend of a friend of mine is offering me the following 12" Powerbook for $1100: 1 Ghz G4 512 MB RAM 40 GB HDD Built-in Airport & Bluetooth Combo With Panther, Office 2004 and Keynote. 1. Do you think this is a good deal? 2. Should I wait for the expo, even if I'm probably gonna go for a second hand PB? Thanks guys.
