I always thought that MS will make something like that. Android phone with "business" app store and docking support for external screen and peripherals. IIRC one of the last windows phones was from HP with dock support. I guess after the windows phone they just gave up.... There was an attempt at making dual screen ms android phone which was a failure (at least from business perspective).

Yes the problem with continuum was just the huge lack of ARM-capable windows software at the time. I think it would have fared a lot better today.
