To be honest I don't think it matters anymore.
Public opinion has already determined the order of popularity..
1) Open source Android platform and it's many different handsets
2) Apple fans with restriced OS and nanny state app development
RIM, Symbian and WM lagging somewhere behind..
What's that got to do with anything? I thought we were discussing mobile phone tech?!
It has nothing to do with it. Games consoles are still considered 'niche' when you compare the penetration against mobile phone usage. Just because Micro$oft have a popular gaming device it doesn't automatically mean they're mobile OS is going to fare just as well
