I prefer to code on my laptop. You may be able to see more on a big screen, but you can't concentrate on more. I have GNU Screen set up with multiple command line tabs that I can switch between using hot keys, which is automatic enough that it happens at least as fast as I can mentally switch. I keep things in a consistent setup (bash on tab 0, editor on tab 1, etc.) so I never have to figure out what tab I need to go to.

When using a large screen, I struggle with figuring out where to look on the screen quickly. I could build habits that would remedy this by distributing things consistently on my screen, but then I'd have to build separate habits for my big screens and little screens.
