Microsoft phones failed.
Windows Mobile, Windows Phone, Windows 10 Mobile — all too little, too late.
But I think Microsoft could succeed with its next device.
Rumor has it that Microsoft is working on a two-screen clamshell mobile device code-named Andromeda that may be branded the “Surface Phone.” (The more likely branding may be “Surface Pad,” or something like that, to de-emphasize the phone function.)
I believe the rumors are true and predict this device could even be teased at Microsoft’s Build Conference in Seattle May 7.
