Does the display matter for a terminal application? As for battery and weight, you are talking about pluggin in various other devices that you presumably don't carry around, so it wouldn't make any difference if you plug it in to the power or not. If you often do carry it (without the other gear), then I can maybe see it, though you can buy a used small thinkpad that can easily run the terminal programs.
