Microsoft MP3 players haven't been around that long, but the Zune has made a solid impact on the MP3 player industry. In 2006 they first introduced their device which was deemed a success. Not too shortly thereafter the second generation came out with small flash and large hard drive versions. The most notable thing about Microsoft's Zune however is that it can wirelessly share files with other Zunes, making it the first player to do so. One can only imagine what Microsoft might come up with next.
