Wow, that's pretty fast indeed. That's good to hear.
When I looked at the recommendations for posting experiences, I haven't touched up on any, so I'll do that now.
The first layout I started using was QWERTY, and I used that for about 7 years, and my max speed was about 80WPM.
After reading about Dvorak, earlier this year, and how much more efficient it is than QWERTY, I decided to make the switch. It was definitely for the better. After using Dvorak for about a month, though, I realized my pinky would often get tired, and I would have to stop typing for a bit. Also, I missed my Ctrl-Z/X/C/V shortcuts, but I put up with Dvorak because it was better than QWERTY.
As recently as Wednesday, November 15, 2006 a friend of mine pointed my attention to Colemak. After reading about it and using the compare feature with the JAVA applet, that was enough to get me switch, but I didn't officially make the switch until the 16th.
Since then, I've been using TypeFaster to help me out, and I practice for about 2 hours a day. I think I might increase that to about 3 and a half.
And I, of course, typed this very, very slowly using Colemak.
