Your video was a little too long for my taste. You maybe could create a shorter video showing the full speed of productivity gained by getting rid of the mouse. I imagine some workflow every programmer does all the time:

- read code - check docs - write code - test and look at logs

I use the keyboard for 80% of my work and regularly people (including devs) are in awe of the speed of my movements. I would even go so far and say that it improves Flow (psychology) by reducing mental overhead (muscle memory).

Best wishes! :)
