IRiver X20
The iRiver X20 is a small, flash memory based portable media player (PMP) from iRiver. It was announced at the 2007 Consumer Electronics Show. Initially only 2 and 4 GB versions were announced but soon an 8 GB was also released. Features
The X20 is a small device in gloss black with audio and video capability, and also has built-in stereo speakers on its back. Additionally, it has a Micro SD slot for expandable memory while also offering recording capabilities via microphone in or line in. It has a mechanical scroll wheel that is used for navigating the device, which can only be used in a landscape format with the controls on the right hand side. The X20 also includes a voice recorder and FM radio. Audio formats supported are MP3, WMA, WAV and OGG. Video formats are MPEG-4 and WMV, and there is also support for JPEG still images. Reception
According to TechDigest.tv, the iRiver X20 performs well as a music player but the screen is too small for video. It also criticised the interface navigation and gave the player 3 stars out of 5. CNET praised the sleek design and display quality, but was not fond of the mechanical scroll wheel. References
