Altec Lansing inMotion iM600

The good: Altec Lansing's iM600 speaker system offers a compact design, great sound, video output, auxiliary input, remote control, FM radio, and a rechargeable battery rated at seven hours of continuous playback.

The bad: The iM600 does not secure your iPod from falling out; its alarm clock feature only works with the iPod; the rechargeable battery is not removable; and the FM radio band is wider than necessary.

The bottom line: Altec Lansing has been in the iPod speaker market longer than anyone, and it shows. The inclusion of a rechargeable battery and an FM radio makes the iM600 incredibly versatile.
