@tiktoktoyatoya ok I did some testing. Here are some screenshots from my tablet, set to 175% GUI scale:
As you might have noticed, text is quite blurry in desktop apps. That's because Windows' high-DPI setting always makes it blurry. But I don't think it would be an issue on a small screen
I have also loaded these pictures into my phone (5") and it seems it would be pretty usable. Except that the taskbar is very narrow, but if the phone has physical back/start/cortana buttons, then it's alright.
