Query: Is NOT supported on Vista

Note that Sansa provides no support for this player on Vista, even though (as I write this in March) Vista has been available to customers for 5 months.You will not be able to update the device's firmware (which is several versions behind as shipped), and Sansa provides no guidance as to when they might (if ever) they will support Vista.(And they wonder can't compete with the iPod?)
