I run my S23 Ultra with a pair of XReal One's, and a folding Bluetooth keyboard (DeX let's you use your phone as a touchpad). It is really amazing in widescreen mode sitting in a coffee shop, reading through technical documents and answering work email. When I'm done, it can all fold up and fit in a (spacious) pair of cargo shorts.
I think Samsung has played the long game on DeX, with an eye towards their collaborative XR glasses with Google next year. As great as XReal has been, I am eager to see a "first-party" solution.
