>>But you're totally discounting the 3rd world market for cheap nokia phones....

Where do you get that? Symbian sales figures are available too, not that it matters any more.

>>MS has already demo'd windows 8 (the full operating system) running on an ARM chip...This (MS's) market is set to blast off.... I'm not saying it will happen by 2013 as do the pundits, but it is just a matter of time (certainly by 2015 or so) before wp9 or wp10 is the king.

You've made the point that markets are finite: with observers saying that Android will hit 1 million daily activations by 2013, why exactly will these people swap to WP? I'm not disagreeing, I'm saying that there will need to be a compelling proposition to draw people away from the dominant Android. What is it?

>>Googles fragmentation problems and lawsuit problems are just the tip of the iceberg. MS did this exact same thing from 1999 - 2008. The were predominant in the market until the fragmentation bit them in the a**. Unless google switches directions, its inevitable that MS or another yet unamed entry will overtake them.

Google does have a problem with its smaller patent library meaning it's harder to cross-license. This could indeed bring it to a crashing halt in some jurisdictions. Lets not treat that as a certainty, though.
