Samsung has DeX. They also did Linux on DeX at one point but stopped.

DeX is pretty useful yes. A bit compromised though by Samsung's latest phones skimping out on the memory side, the S22 has the same amount that the S10 came with 3 years ago. DeX really needs lots of RAM as you'll typically have multiple apps open unlike on a phone screen. Once you run out browser tabs will start refreshing as soon as they so much as lose focus...

Really 12GB or even 16 would be much better for DeX. But you can only get 12 now on the ultra and not everyone likes massive phones.. I don't anyway.

Even if 8GB may be enough now it won't be as apps get bigger. It was nice in the beginning on my S8 but the last years I had it I hardly used DeX anymore as the experience became too slow and the refreshing too annoying. For example, just moving away from a form in a browser tab to copy something from my password manager would result in the browser tab refreshing upon return and the form inputs lost..

I don't particularly care about that either, I just want something I have actual real control over, that's updateable indefinitely, and doesn't shove crap in my face or spy on me
