The iPod 2nd generation was released on July 17, 2002. It had a few hardware improvements such as a redesigned hold switch, a cover for the Firewire port and slightly more rounded body. The main improvement was the scroll wheel switching from a mechanical wheel to a touch sensetive wheel which is used to this day. It also sported a larger hard-drive capacity, now offering 10GB or 20GB versions. It also was the first iPod with Windows support, through the use of Musicmatch Jukebox, a third party bundled application as iTunes had not yet been released for Windows yet. Apple continued to sell iPod 1st generation 5GB versions into this products lifespan.
