Until recently I thought of Dex as a novelty samsung feature kind've like the VR sets were a couple of years ago. However, recently I was frustrated with how slow my desktop windows 10 Pc is. It isn't that old, but it has a terrible Intel Pentium processor from 2017. The desktop itself, looks good, doesn't take up much space and has a touchscreen 22 inch display. So I figured, why not see if Dex could be a good substitute to run on this pc instead of windows 10 in slow motion. Well it works flawlessly. I don't know how Dex works, but I'm guessing it runs off of the S20 Ultra snapdragon processor and the 12gb of ram because Dex runs great, and instant. I don't mobile game much so Idk if it would be as fast playing a game but it definetly runs everything else fine. Considering I have Microsoft Office, the mobile apps work just as well as the pc desktop versions do, for me anyway.
