Samsung has stores?
My mom refuses to use dex, I found it to be great as a basic workstation. Definitely removes the need for eg a chrome book. Does not replace your power user machine however
In Australia & the US, they have quite a few.

The Samsung DeX Station (https://www.samsung.com/au/galaxy-s8-accessories/dex-station...) is no longer manufactured which is a massive let down. It does however still work with the S10+, and I presume the S20. The ability send a network cable straight to the phone was pretty handy for a few situations.
