I'm thinking of picking up a MacBook, and would need to sell my PowerBook G4 to make that happen. This is a last-generation model; it's the fastest 12" PowerBook Apple ever made.
Here are the specs:
12" PowerBook G4, 1.5GHz
512MB RAM, PC2700 (maximum is 1.25GB)
2x USB 2.0 ports, 1x FireWire 400
AirPort Extreme wireless card (802.11b/g)
The machine is in excellent functional and cosmetic condition. It includes two AC adapters, and the battery still holds a decent charge. The SuperDrive sometimes has problems loading discs with especially slick label surfaces, but I've had that problem with other laptops too, so I don't think it's a defect with the drive.
Apple still sells this exact configuration (but only including one AC adapter) as a refurbished unit for $1200. I'm looking for $900, or best offer. I've seen older 12" models (like the 1.0GHz and 1.33GHz revisions) sell for upwards of $800 on eBay, so I think $900 is fair.
If you're interested, shoot me a PM or e-mail firstname.lastname@example.org.
