Re-read my post where I specificually said "Other than the desktop market". That would include Windows since they are the one with 90% market share. Also read where I (and many other tech experts) have argued that success was a fluke.Windows worked out pretty well being an open platform that can be installed on x86 hardware.
I also disagree with your assertion of Windows Mobile - Sure it was crap, but it still was hugely successful until the iPhone came around. Of course the cellular market is rife with competition from several other platforms. Open OR closed, you have to make a good product.
Just because a platform is open doesn't mean it'll be a success. Doesn't mean it won't be, either.
The quote I was addressing was that open platforms always win. I have yet to see that be the case anywhere outside of the desktop market. My point stands. Who cares about quantity - it's quality and your ability to leverage prior successes. That can be had even on closed systems.
I don't know but just look at Google as a company and see how they've grown with this mentality. Sure they are the smallest of all the OS's but I wouldn't count them out just because of it. Their platform will continue to evolve, its on version 2.0.
Google's approach is internet based services which is platform agnostic. They don't care about hardware in as much. It's kind of hard to say who they are competing with, if anybody. The only OS they have is Android, which is the same flawed approach of Windows Mobile. Who knows what Google is planning, but whatever it is, its not a desktop based one.
WinMo isn't doing great, but you look at the ZuneHD, and talk of WinMo 7 and you can't help but think that when its released it will be on par with Android and iPhone OS.
But that's the future - anything can happen when you make a plea for "some day" what matters is what is happening now.
