I've already converted my music to the iPod format and downloaded a bunch of music from iTunes. Why should I buy a different player and be forced to re-import my music collection and re-buy the music I bought on iTunes. I'm a fan of Microsoft but they seem a day late and a dollar short in my eyes.
I doubt MS will be targetting you, but they will be targetting the havent bought yet and those looking for an alternative device.Which the havent bought yet, which probably is a far larger market then the installed base(unless iPod somehow has hundreds of millions) is the biggest prize and allows for MS to move in. Kind of like the Nintendo DS which is targetted at gamers and non-gamers and has become a huge success and has found people buying it who have never owned a system before because of non-game games like Brain Age, the DS btw is the most succesful handheld game device in history facing an installed base of hundreds of millions of gameboys.
