It's the gap where you still have a full-time job to do along with those expectations that I fall down. :( Maybe it's to late for me?
That aside, I have never had any problem with productivity as a developer. As a "typist", yes, but not as an author of software. It just never comes up. Do I feel less "cool" when I am in a room with people looking at me type? Hell yes. But am I actually getting things done slower? Probably some things. Typing commands, yes. I could be faster there. Typing code? Maybe.
Just adding the perspective of a long time 6 fingered typist (occasionally 7).
