Microsoft has launched Zune portable music player today. It retails at $250 at an cost equal to that of the Apple's 30 GB I-Pod Category. The main feature is that you can share songs and photographs wirelessly among different Zunes. Compared to I-pod it is a bit larger and bulky, also heavier. Battery lif eis same for songs ( 14 Hrs ) , video playback time is 4 hrs compared to 3.5 hrs of I-Pod.
Even the cost of a song is comparable at 99 cents. I just think that Apple has the First Mover advantage to It which will not be that easy to snatch away from Apple.
