There is an increasing amount of evidence that Microsoft is preparing to drop all of its different brands of Windows -- Windows Phone, Windows 8, Windows 9, Windows RT -- and simply call them all Windows. The idea would be that, in the mind of the consumer, Windows is just Windows, and that all of these different names and flavors are just confusing. Getting rid of all that complexity and returning to the old way -- where Windows is synonymous with personal computing -- would certainly be a coup for Microsoft.
