Okay, I tried Dvorak for one day, and was pretty comfortable with the home row.

Then I read wikipedia some more, found colemak, and decided to try it instead.

My Qwerty speed: 60-80wpm

After 2 days of Colemak practice:

50wpm on the first practice test (STNE keys)

20wpm on the second practice test (adding RI).

13wpm overall, on online typing tests using all keys.

One thing that I've noticed is on the second test I'm much MUCH slower at hitting my left-hand keys (especially S).  In fact even though R and I are the new keys, I'm hitting those faster than S.  This is frustrating to me and I find myself just doing the first test over and over since there's virtually no disparity in timing on that test (that's probably because I virtually have the first test memorized). 

The fact that Dvorak is imbalanced in favor of the right hand is actually looking pretty nice to me right now...

Will my left hand ever strengthen up to rival my right hand?  I mean I was already hitting the majority of keys with my left hand with QWERTY, and that doesn't seem to have strengthened it.

Perhaps there should be a right-handed and a left-handed version?
