I tried out Dvorak for a while, but then every time I had to help someone with their computer, or go to a client site, I was struggling to adjust to the 'normal' QWERTY layout. I'm a Colemak user and while your point is on the mark (I do feel a bit stupid when typing on a qwerty keyboard now) I feel that using Colemak is still worthwhile for me as I spend over 90% of my typing time on my own computer and I type so much every day that I feel its worthwhile for me to optimize for that case, even if it makes the other cases much worse.
