>>I'm not the person you need to argue with on this. I simply pointed out a contrasting view. In the end, it's all opinion and wild guesses.

Fortunately we're able to assess figures ourselves. US sales figures for 2012 show Android phone sales being 51.2% compared to iOS's 43.5 percent. There's a suggestion that iOS subsequently inched past Android, but the main point is that those 2 OS claimed 95% of sales with everything else, including WP, fighting for the remaining 5%. It's a 2-horse race, period.

Next, check out the MobiLens study looking at smartphone use, not just what got sold last year. Android 52.3%, iOS 37.8%. Those two OS have >90% of smartphones being used.

Next, looking at tablets: iOS still rules but it looks like Android will have 49% sales there as well with iOS somewhere around 45% in 2013. Perhaps somebody will present this as a Windows win, since other OS are fighting over 6% share in tablets which is 20% more than the share they're fighting over on phones. ;-)

Windows dominates the Desktop which is in steep decline as well as some server markets. It also has lots of very expensive enterprise software that won't run on other platforms yet. Which leads some wags to refer to Windows as the backward compatible layer. Certainly not the reliable source of excitement and business advantage that MS offered when we were young dudes.
