I&#x27;ve been able to (and have done so) plug my android phone into a usb hub with mouse and keyboard and into a 1080p screen for quite a few years now.<p>Of course, there&#x27;s relatively little that truly takes advantage of that set up, and making the user experience more pleasant would make a huge difference, but android understands mouse and keyboard input just fine.  Microsoft may be somewhat further along on this front, but I don&#x27;t think it&#x27;s as much as you think - the apps that can run in this way are not full windows applications, and there are relatively few of them at present.
