Sullivan said it is possible that Microsoft will eventually have a single app store for buying applications that work on different devices. So far, Windows Phone and Windows 8 share the same kernel, but are not synonymous and need to be different to allow app developers to accommodate different screen sizes and resolutions and many other factors, Sullivan said.
Windows Phone has attracted honors and recognition for some basics, including its "live tiles" concept on the interface that allows a person to set up a "theoretically endless" number of applications to run on the home screen, Sullivan said.
BlackBerry picked up some of the live tile concept in its new BlackBerry 10 smartphone, the Z10, and some Android phones are even showing design (if not function) similarities to the live tiles concept, Sullivan said.
"It's flattering to see others adopt elements of the Windows Phone design and philosophy," he said.
