First look over at ZDNet at Apple’s long overdue seventeen-inch PowerBook G4, which is just now starting to arrive in stores after being announced back in January. Looks like it’s worth wait, with a 1440×900 pixel high-resolution screen, built-in 802.11g, Bluetooth, FireWire 800, a DVD-R/CD-RW drive, 512MB of RAM, a 1GHz processor, and a backlit keyboard with an ambient light sensor that adjusts keyboard and screen brightness based on how bright it is in the surrounding area.
