I want something akin to a desktop with a big screen at home, but which I can also bring to a coffee shop. I don't want to have to fiddle with ugly docks, usb monitors, etc. Those things are a PITA.

Wouldn't it be better to just connect a normal laptop to a bigger screen?

That's what I'm doing now, it's a pain in the ass

It means I can only get a big screen when I happen to be where my big screen is (even a different room in the house is a pain) and every time I connect Windows decides to reposition my apps differently, and 10% of the time I have to reboot because something janky happened to the screen connection
