FYI - The DeX dock has a fan on it to prevent overheating the docked phone. I got one to just play around with. Turns out, for normal (non-dev) usage, it can already replace a laptop in an office setting, even without Linux mode. BUT - undocking closes apps, so re-docking doesn't go back where you started. That gets annoying when you redock after taking the phone out for a quick coffee run or bio-break. As a result, I'm back to the laptop until that gets fixed.
