Microsoft is set to arrive at new heights this fall with the release of Windows 8. Along with Windows 8, Windows Phone 8 is supposed to finally catch up with Google Android and Apple iOS. The install base of Microsoft is amazing in size. With Windows 8, customers will get a single user interface across PCs, tablets and smartphones. This will drive many Windows users to adopt a Windows Phone 8 device this fall.
The iPhone 5 could stop or slow the rise of Windows Phone 8 if it is a complete stunner. So far though it does not look like it will. Based on the rumors so far the iPhone 5 will be a solid upgrade from the iPhone 4S, but not a quantum leap. It will have a larger screen, possibly LTE and more horse power.
Unless Apple still has a secret we will soon see three smartphone OS that have similar market shares. Both Android and iOS will lose market share when Windows Phone 8 launches.
