The "original" Apple iPod classic (Sixth Generation) was equipped with an 80 GB or 160 GB 4200 RPM ATA-66 hard drive, capable of holding "up to" 20,000 or 40,000 songs in "128-Kbps AAC format," or "up to 100 hours" or "up to 200 hours" of video, respectively.
Externally, the iPod classic models were similar in design to the iPod 5G Enhanced, featuring a 2.5" color LCD with an LED backlight (320x240, 163 ppi). However, they used slightly thinner cases with either a silver or black anodized aluminum front and a chromed stainless steel back, a change from the white or black polycarbonate fronts of previous models. Notably, these were the first "full size" iPod models not offered in white.
The iPod classic models also delivered significantly improved battery life compared to their predecessors: 30 hours of music and 5 hours of video for the 80 GB model, and 40 hours of music and 7 hours of video for the 160 GB model. A downside was that these models no longer supported video out directly from the headphone jack, only from the dock.
The software was substantially upgraded with an interface inspired by "MacOS X Leopard" and the iPhone's OS X, featuring a Cover Flow option for album selection. It also came bundled with three games: iQuiz, Klondike, and Vortex.
