If Microsoft ever release a player watch out

Apple would have greater recognition (been around for years) and marketing power over Cowon and Rio etc, because they don't just specialise in DAP's, but get a majority of their income from Mac sales
I also think the market share is like that because iPod was one of the first HDD audio players around. They also pick up the Apple fanatics market share, as well as the female market share (who go more so for the look of the device). They've also got that scroll wheel, which has become an unofficially patented navigational advantage for the iPod
I would probably have got one myself if they had a better battery system (better life+replaceable) and better format support.
Personally, I've got a Cowon iAUDIO M3 which I'm very happy with. FLAC and Ogg support, replaceable 14hr battery (35hr battery life in the M3L version), FM radio and voice recording. Though no screen on the main unit (can be both advantageous and disadvantageous)
My point here though is that Cowon only sells DAP's as far as I am aware, and Apple would have greater financial and human resources for research, engineering and marketting and the iPod is a great device because of this. (though Cowon, and other DAP producers are holding their own in various markets)
iPod is also becoming a synonym for DAP's in Australia too, somewhat disturbing, but understandable in a sense (digital audio player is a bit of a mouthful when referring to such a device)
BTW, is this statistic for a specific country (USA?) or global?
