Not even for gaming, but just general office work/watching videos/whatever else you can do inside a browser.

I still want a laptop thingie with a battery under the keyboard, some ports, and where the phone acts like the trackpad when docked. I know that it would be phone specific due to the size, but seriously that would be amazing. The "laptop" can be pretty cheap being just a keyboard, battery, and monitor as well.

Imagine a spot where someone wakes up, has their phone in a dock to stimulate an alarm clock, grabs it, and drives to work (with android auto, obviously). Next scene they arrive in the office, plug their phone into a dock with keyboard/mouse + monitor attached and start working seamlessly. Later they sit down in a café with just a tiny keyboard writing some emails on their phone, go back home and Screencast videos to their TV.
