I switched to Dvorak back in the summer of 2005 and I've never looked back. Colemak may have been a better choice for certain metrics on certain keyboards, but one that cannot be stated enough for Dvorak is the way your hands alternate keys so much more than they do on QWERTY. I'm not sure if that has been studied for Colemak.<p>Thoughts on changing keyboard layouts:<p>1) If you're gonna do it, I agree with this article, touch typing = #1 priority. You're not going to see a colemak keyboard, most likely.<p>2) QWERTY actually seems to work pretty well for big thumbs on a small screen. I don't use tablets, so I don't know the state of affairs on Android or iOS keyboard layouts. This has notably not been a problem for me, even though I was initially concerned about using BlackBerrys (oh 2005 me..)<p>3) IRC/Instant Messaging are a massive way to learn how to type because you'll prioritize learning words that you type often, and natural patterns for you.<p>4) Buy a better keyboard if you're gonna go to this effort for your hands. I swear by my Kinesis Advantage Pro.<p>This process is frustratingly slow, but after ~3 weeks of going cold turkey, I have not once switched back. I was even a sysadmin for 1000's of desktops in labs, and it took 2 seconds to switch them to dvorak and back.<p>Finally, while we're at it, if your company offers ergonomic consulting, <i>DO IT</i>! You'll be amazed how much more comfortable your typing is when you've fixed how you sit, your monitor height, and your keyboard tray.
