I did Samsung dex for a while, its ok as long as you don’t want low level access to what you connecting to.

Now I switched to a gpd micropc 2 and its built in ethernet, sd card, usb a and c sockets and native linux make it so much more useful. No longer do i need dongles or other rubbish.

Plus it will do multiple monitor support, something dex struggles with. The keyboard is a little small for touch typing but the former factor is worth the trade of for me.
