Microsoft’s early experiments with hardware were utter failures. First it experimented with Zune, a range of portable media players that compete with iPods. After its poor sales, in 2011, Microsoft announced discontinuation of all Zune hardware.

In 2010, Microsoft experimented with Kin- a family of Smartphones targeted at the social networking users. Microsoft spent around $1 billion focusing on these phones but just 3 months after launch, the company gave up on the device amid sluggish sales.  

This is more than enough to know Microsoft doesn’t know how to work with the mobile hardware except the Xbox devices.
