completely gapless playback and AAC audio playback. The Clip+ replaced the discontinued Sansa Clip, with which it shared nearly identical hardware aside from the microSDHC slot. Playlist support The Clip+ User Manual provides instructions for copying files and folders of music from a PC onto the internal and/or external memories, using the Windows Explorer application. It also provides instructions for creating playlists, using the Windows Media Player. However, varying degrees of success have motivated many users to experiment with other applications, such as Media Monkey and Winamp. Slot Player slotRadio Bundle slotRadio player slotMusic player Sansa Fuze The Sansa Fuze, released on March 28, 2008 in capacities of 2, 4 and 8 GB, is a portable media player with a 1.9-inch color display and a thickness of 0.3 inches. It also features a 40-preset FM radio with FM recording, a voice recorder, and has a 24-hour battery life on continuous audio playback. Storage is expandable via a microSDHC slot. Firmware 1.01.22 enabled FLAC and Ogg Vorbis playback. Like the Clip, the Fuze went through two hardware revisions, the first based on the AS3525 (like the Clipv1) and the second based on the AS3525+ (like the Clipv2, Clip+ and Clip Zip). The latest firmware releases, depending on hardware version, are 01.02.31, 02.03.31 and 02.03.33. Sansa Clip Also known as the m300, the Sansa Clip was released on October 9, 2007. The player is similar in size to the second-generation iPod Shuffle, but incorporates a removable clip and 4-line OLED screen (one line yellow, three blue.) The Clip has an FM tuner/recorder and a built-in microphone. The flash-based player ships in capacities of 1 GB (available only in black), 2 GB (available in black, blue, red and pink), and 4 GB (silver and black). In November 2008, black and silver 8 GB versions were advertised in the UK. Midway through production of the Clip, SanDisk updated to a new hardware design based on an updated Austriamicrosystems SOC. The updated design moderately improved battery life by introducing a more efficient ARM9E processor in place of the previous ARM9 core. Aside from requiring different firmware upgrades, there were no functional changes to the software. The updated SOC would however form the basis for the Clip+ and Clip Zip products. Rockbox was released for the Clip v1 on November 21, 2009, and then for the Clip v2 on May 14, 2010. Firmware version 01.01.29, released
