With so many iPod docks in the market, the new entrants need to have that something special in them to really capture your attention. What makes the iSymphony's M2 DVD Micro Music System with Built-in Universal Dock for iPod different is that it has a Progressive scan DVD player. The M2 also features a 14 in one media card reader, 50 watts of output power, clock radio functions, MP3 and WMA playback, an AM/FM radio, and it comes with a remote control.

The M2 is also compatible with the shuffle and it can play music off of USB drives.
