My wife had a Windows phone and reported that the Onedrive/Office support for Android was actually better than on Windows phone. shrug.
(Currently dealing with Onedrive sync having self-destructed on her laptop, she is now much less of a Microsoft fan)
I have no interest in dockable phones or app handoff or any of that; never saw the point of it when using iOS + OS X, don't miss it now that I'm on Windows/Linux/Android.
