What I found really quite suprised me:
- It's way easier to re-train yourself than I thought it would be (faster, at least...it still requires a massive amount of concentration)
- QWERTY is beginning to feel horribly inefficient (I'd read before that your fingers do less walking with Dvorak but I never appreciated just how much more. It feels like even less movement with Colemak.)
What are your experiences with alternative layouts?
