The iRiver S10 might be small and compact in size, but it still manages to pack in some amazing features--including 2 GB of internal storage, a 1.15-inch full-color screen, a digital FM radio, and more, all in a sleek design. With support for MP3, WMA, ASF, and OGG (including Q10) audio file playback, the S10 supports up to eight hours of multimedia playback powered by its internal Li-Poly rechargeable battery. Easy to use, the S10 features iRiver's legendary iRiver D-Click system interface. The S10's usability goes far beyond the typical multimedia playback abilities that most MP3 players boast. In addition to audio playback and picture-viewing capabilities (the player supports BMP picture files), the S10 supports a voice recording mode--a great feature for students and business users--and even allows users to use its ample 2 GB of storage space as a mass storage device. Other great features include a digital clock, an alarm, and a timer. The S10 is compatible with Windows 98SE, Windows Me, Windows 2000, Windows XP, and Windows Vista, and Mac OS by 10.2 and later operating systems. Sporting speedy USB 2.0 connectivity, the S10 measures 1.65 by 1.18 by .42 inches and weighs a scant 0.62 ounce. The player is backed by a 1-year limited manufacturer's warranty.
