It's actually really good. I can wirelessly turn my TV into a 4K Android tablet, and with a Bluetooth keyboard and mouse, it turns into a computer.
Same with a USB cable plugged into my desk's monitor to HDMI. If I didn't require a computer for development, I would not buy computers any more.
Wireless Dex is limited to 1080p and wired one goes to max 1440p
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.
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

Samsung's Dex dock thingy still exists and can be useful when travelling - most hotel rooms you can plug into the TV with HDMI, so a phone and keyboard is less trouble than carrying a full laptop. If you could rely on finding a keyboard (even just a USB one) in any hotel room it would be a lot better. And hopefully with apple shifting to ARM there'll be a lot more desktop software that runs properly on phone processors.
Can't remember who did it, but seemed like the consensus at the time was that all you end up with is the worst of both worlds.
Hybrid devices only rarely end up successful it seems.
