Microsoft is still struggling to come up with a Zune platform that competes with Apple’s iPod/iTunes juggernaut, reports Electronista:

Microsoft has revealed that it has sold two million of the music players since their launch in November 2006, revealing relatively flat growth for the device lineup.

The results leave Microsoft with just a fraction of Apple’s US share and with comparatively slow development. The company has primarily affected marketshare of Creative, who has dropped from four to two percent marketshare year-over-year, but has been unable to dislodge second-place SanDisk (at 11 percent) or the top-selling iPod.

Apple, in its latest quarter, sold 10.6 million iPods, or more than five times Microsoft’s cumulative sales to date.

At this point, Apple’s more likely to cannibalize it’s own iPod sales with more advanced devices, like the iPhone, than Microsoft is doing with the Zune. Microsoft’s recent Zune update moves the platform forward, but not as quickly as Apple is doing with the iPod/iPhone.
