In an email sent out to several company executives and partners, the executive vice president of Microsoft's Windows and Devices Group Terry Myerson has made it clear that the company is committed to the OS platform and is also working on new mobile devices.

Microsoft has been long-rumored to be working on a device dubbed Surface Phone. In fact, the company has dropped several hints in the past effectively confirming a Surface branded phone is indeed in the making, with CMO Chris Capossella even calling it a "breakthrough device."
