Products like the iRiver, iTrip and other FM broadcast devices are fairly popular among the mp3 player crowd, especially for those who travel a lot. Not all stereos had the proper RCA input to plug straight in, and nearly every vehicle has a radio. Normally, you'd have to buy the transmitter seperately. Now, however, the MuStik A200 is an mp3 player that has the FM transmitter built into it. Weighing in at a miniscule 44g, the tiny mp3 player only has 1GB of space for music, but future versions may expand that. It plays various media formats, including some videos and pictures, as well as eBooks. The product is already available online, depending on where you are.
