Yes, but that wasn't desktop Windows. In fact it inflicted some brand damage on desktop windows, back in the Win8 era, by moving all the new stuff to Metro.
(I'm not sure there's ever been a proper decent portable/handheld that ran Real Windows; there's tiny laptops from the Libretto to the GPD Pockect, which is a nice machine. Or there were handhelds that ran Windows CE back in the PDA era. And I've seen very cheap 8" tablets. But a phone-size form factor? Not quite. I suspect the never completely fixed UI scaling is a problem there.)
Trying to press controls intended for desktop Windows on that tiny screen would be an exercise in frustration. Trying using RDP software on your phone and see how productive it is.
If I have to make two remote desktop connections lasting ten minutes each per workday from the beach, which machine am I bringing: my phone/this? Or a full laptop?
