I bought a final-revision version of the PowerBook G4 15". It's essentially three months old and is in excellent condition, so if you're looking for a like-new PowerBook, this is a great machine for you.
The specs are as follows:
* 1.67 Ghz PowerPC G4 processor
* 1GB PC2-4200 DDR SDRAM -- all on one chip (so you have the other slot free if you want to add additional memory later on)
* 15.2", 1440 x 960 resolution widescreen display
* ATI Mobility Radeon 9700 Graphics Card, with 12MB SSR SDRAM and dual-link DVI
* 80GB Hard Drive
* 8x DUAL-LAYER SuperDrive (DVD+R, DL, DVR+/RW, CD-RW) -- Apple's fastest SuperDrive EVER, and the only Dual-Layer Drive you'll find in any Apple laptop
* DVI, VGA, S-Video, and composite video out
* Combined analog and optical digital line-in; combined analog and digital line-out, stereo speakers, microphone
* 10/100/1000BASE-T (Gigabit) Ethernet
* Built in 54-Mbps Airport Extreme, for wireless internet connectivity
* Built in Bluetooth 2.0+EDR
* Built-in 56K V.92 modem
* Illuminated keyboard with ambient light sensor
* FireWire 400, FireWire 800, and USB ports. Type I/II PC Card Slot
I have the original box and DVDs, as well as all the manuals and documentation (unopened). All the cables come with it, and I've opened none of those. Even the power adapter has the original factory plastic around it, so it's not scratched up and is good-as-new. I can take pictures of any item upon request.
If you're looking to save some money over buying a new laptop, and you like some of the unique things that the final generation of PowerBook G4s offer (including lightning-fast speed at things like Photoshop, 1GB of memory on a single chip, and the highest resolution ever on an Apple 15"), then this is the laptop for you.
