10% of my time is 4-8 hours a week. And I'm writing up those requirements, tests, etc. someplace, so I've got hands on keyboard far more than 10% of my time (usually in a vi). Seems like a good opportunity to optimize. I made my choice...not because I 'like it', but because I've been doing it both ways since the 80s and this works.
In the end, tho, you don't understand the argument, don't know the tools (know enough to get stuff done doesn't count), haven't walked in the shoes, but you're absolutely certain all us vi/emacs users are wrong. I mean, I've heard this pissing contest since the Win3 days, so I don't expect much intellectual rigor, but most people who feel the need to "well ackshually" keyboard jockeys at lest take the time to google up something like AskTogs infamous "I spent $50m to prove mice are faster" (for Apple, trying to push the Macintosh, with none of the research ever published AFAIK) to 'prove' how deluded we are. There is actual published research out there covering not just speed but ergonomics and accuracy; it's pretty inconclusive all things considered, and very dependent on the use case the researchers decide to examine, so really easy to cherry pick so you get to win arguments on the internet.
