If we go by an article published by Wall Street Journal today, we could get a new smartphone from Microsoft. According to WSJ, Microsoft is testing a new design for a smartphone. The screen size of the smartphone is between four to five inches. A smartphone manufactured by Microsoft is inline with its new strategy. Microsoft has recently launched its own line of windows tablets called Surface. Surface tablets run on Windows RT and Windows 8. A smartphone from Microsoft might not go down well with its partners who presently manufacture smartphones based on the Windows Phone OS. But it will be good to have a phone from Microsoft.
