How are they more keystrokes between one screen and N screens? Don't you have to switch windows regardless of their visibility? I mean if you copy then paste elsewhere you still the same number of key strokes, don't you? Maybe I'm missing something.

Regardless what I'm suggesting, and I believe OP too, is NOT to replace your setup with a mobile one, only that they can complement each other. Namely if you are on your way somewhere, you do not have to stop programming, you can still do it even though in a different way, so I do not believe comparing them helps. The point is not to convince somebody to go from their favorite setup to something they like less, rather to show other ways in which some parts of the process are still acceptable on the go. Nobody is suggesting to remove a screen or keyboard.
