That's what IDC is guessing. See their prior predictions. I think its laughable given the current distrust of Windows and loosing ground with what it does have. Add to it those stupid and insulting "smartphone beta tester" commercials (make us all look like idiots). Still, Windows is the dominant computer OS, and Microsoft does have deep pockets, they do have the potential to make a significant comeback if they play it right (not that I have seen any right moves). One person noted MS is in better position to make an integrated environment then Google, doing a similar Desktop/Laptop-to-SmartPhone linking (via SkyDrive) then Google (can which currently has a marginally useable OS product in its Chrome OS). IMHO, Android will suffer far more then iOS, becuase MS can actually produce something close to what Apple has built with that they have now. That is IF MS can convince people their new OS is really as good as they promise.
