>>>If you believe those numbers... 2.8 million activations a week * 52 weeks = 145 million a year * 3 years = 435 million activations... enough to give everyone in the US a phone ( man, woman and child), and still have enough left over to give another one to every male. Balderdash.... the numbers just don't hold up..

But you're totally discounting the 3rd world market for cheap nokia phones.... 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. Any entry in the market takes time to ramp up. 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.
