iPod first generation (October 23, 2001)

From CNET's review: Our favorite part of the design by far is the scrollwheel used to navigate the menus. When holding the device in one hand, it's possible to move through every song, album, or playlist in mere seconds. Unlike other jog dials or button navigation systems, the scrollwheel accelerates as you turn it, allowing for the kind of maneuvering that's necessary to rapidly peruse 5GB worth of MP3s.
