A question to all developers working on 12 and 13 inches laptops. Do you spend most of your time connected to an external monitor or do you use the laptop one? My instinct is that there isn't enough space for two side by side windows of code but of course people working on 24" monitors would say the same about my 15.6" screen.
I had a smaller 13 inch laptop before that packed a punch but almost exclusively on the docking station and connected to screens, if I would on the sofa and thought I needed to do something really quick, I would grab it but it was painful. People just get used to things though, there are stories of people writing detailed packages on their phone sure!
Even now on 17 inches, I still use it exlusively on the dock with screens!
I still use a 2019 MBP and I can't work on just the laptop screen. My laptop screen usually has one fullscreen window at all times; tmux, or a browser window; all the main work gets done on the big screen.
