I decided to ditch qwerty for dvorak a while ago just because i didn't know colemak was better back then, but you wanna know the thing that finally drove me away from dvorak?
YOU HAVE TO USE 2 HANDS FOR ALL THE STUPID KEYBOARD SHORTCUTS.
Anyway, my motor skills are a bit confused from switching twice, but I've never been more comfortable then in Colemak, so thank you Mr Colman! =)
