The Zune has been killed by Microsoft, but will still be supported if you have any problems with the device.
Today, Apple will kill the iPod classic. In a few years, the nano will go away too. The future of music is in mobile devices, not in standalone ones. To me, this move is forward thinking.
The difference between the two companies is the strategy: Apple will not announce the iPod’s death. It will just go away as an obvious circumstance. For some reason, Microsoft feels as if they owe an explanation.
