The Apple iPod (Third Generation - Second Revision) was equipped with a 10 GB, 20 GB, or 40 GB 4200 RPM ATA-66 hard drive, capable of holding "up to" 2500, 5000, or 10,000 songs, respectively, in "128-Kbps AAC format." It featured a "2-inch (diagonal) [monochrome] LCD display with blue-white LED backlight" housed in a case with an "iBook white" front and a stainless steel back.
This third generation introduced several hardware improvements over earlier models, including a thinner, lighter, and more rounded design, and a "dock" for easy connection to a computer and stereo systems. The now-backlit solid-state buttons were moved from around the touch wheel to above it, a change that drew mixed reactions. However, the increased skip protection (up to 25 minutes) was a welcome feature.
Software enhancements included greater customization options, a voice recorder, games, and an alarm clock. The estimated battery life was eight hours.
