Microsoft is still toiling away at the Zune, but there isn't a whole terrible much to show for it so far in regards to market impact. They just broke the 2 million mark, almost a year after they hit 1 million in May 2007. That means growth has hardly accelerated since the second-gen players hit the scene. Zune's overall market share has grown from three to four percent, but that's most likely a steal from Creative (which sunk from four to two percent) than a steal from Apple or second-place SanDisk (with a billionty and 11 percent, respectively). But don't worry, we're sure that 2.5 update is going to change everything.
