This isn't about Windows Phone specifically, but I think it's something we're gonna start running into more and more as people upgrade to Windows 10.
Has anyone found an actual use for the Microsoft Phone Companion app? It seems to have replaced the Windows Phone app, which was nice for transferring photos and music, etc. But all that seems to have been removed from the Phone Companion app, leaving it powerless to do anything but tell me my phone and PC are "the perfect pair." Are we still able to somehow transfer files with it? Or really, use it for anything? If not, what is the best option?
