The greatest thing about the Sansa Clip is the mobility. You can literally clip this thing anywhere and rock out on the go. The Clip has a built in rechargeable battery that juices up through your USB port, there is voice record and radio abilities, it weighs in at less than an ounce and is a half inch thick. The display lets your scroll through albums, songs, artists, and stations. The FM mode lets you program 40 presets and even sync up with your gym’s TV sets. Of course there is also big sound from this tidbit of a player. Definitely a convenient machine. Oh, of course it jams up to 4G of your mp3s in its little body!
