In devices of this size Samsung and Sansa have decided that requiring the use of an extra cable doesn't make sense. Instead the USB connector is built right into the player itself allowing the U3 to connect directly to your computer. Unlike the Express that sees the connector protected by a removable cap, a slide switch is used to push the connector out of the U3's body. When connected the U3 acts as a mass storage device allowing you to drag and drop songs directly from the file system, or through the media software of your choice (Samsung provides their own software).
The format support ensures the player is compatible with most of your music, even if you use subscription services such as Napster and Rhapsody. However, the lack of AAC support means the U3 can't play songs that have been downloaded or ripped from iTunes. An integrated microphone records voice in MP3 format, and despite the presence of both recording and FM radio, there's no support for FM recording.
