I have been using Qwerty for more almost 10 years now, and my average speed was around 70 WPM, although sometimes I peak in the 90s for very short durations. This year I was writing my master thesis and I programmed over 80 thousands lines of code + around 60 pages thesis report + presentation + miscellaneous. Of course, this has put stress on my wrists and I was already suffering from some kind of injury in my left wrists, which I was not sure if it is due to typing fast or not. Consequently, I was looking for alternative keyboard layout and I searched around to find a bunch. I first tried Dvorak for 2 days , 2hour/day, but i didn't like the L position, Copy and paste shortcut, and the {} were very far away. Also, I wanted something to reduce the movements and distance traveled by my finger. Then, I found Colemak, Carplex, workman, etc... and i decided to try Colemak first . Now, I had a break for 5 days from university, and I needed to change to Colemak as fast as I can and regain at leas half of my Qwerty in four days. Here is my experience after training for 4 continuous days from 1p.m to a midnight.
1- after typing in two positions, while I am sitting and while I am sleeping on my belly, I noticed that there was no tiredness and pressure at my wrists at all, and typing was very pleasant on the wrists even for longer periods of time +8hours. For the first day, I felt all the pressure on my index, shoulders, triceps and traperizus, and the next day I woke up, there was a huge muscular stiffness and tension in my right shoulder, triceps and upper back, as if I went to the Gym. What I found is that this Layout actually trained these muscles for me by putting pressure on then. I especially notice the effect when I am typing on my belly because it requires shoulder strength to sustain the hands on the home key ( at least thats what I think). I do not consider this as a down side of the layout, but rather as plus because after typing four 4 days my upper back strength seems to have improved and.
2- I personally think that hand alternation is usually faster than rolls but it takes longer time to achieve high speeds in alternation because one must memorize words and how to switch hands without thinking, and if properly mastered, one can type almost two characters at the same time using both hands, but at this point I do not care too much about hand alternation (Dvorak), as much as I care about reducing the typing effort, and keeping important short cuts in the same place as Qwerty.
3- Although this layout doesn't concentrate on hands alternation as Dvorak does, I consider it a winning layout because it is easy to learn and promising to be faster than Qwerty. Here is how fast I learned to touch type in just 4 continuous days.
I was using the following typing tutors:
TypeFaster, Mavis beacon, & Stamina
/*********************** day 1 ****************************/
I learned to touch type the layout in less than 3 hours, and by the end of the days my speed was
Colemak:16 WPM
Qwerty : 45 WPM ( dropped)
/*********************** day 2 ****************************/
Colemak:21 WPM
Qwerty : 20 WPM
/*********************** day 3 ****************************/
Colemak:27 WPM
Qwerty : 10 WPM ( touch typing)
/*********************** day 4 ****************************/
Colemak:35 WPM http://hi-games.net/typing-test,300/watch?u=4468
Qwerty : less than 10 WPM (I cant touch type quickly, I have to look at the Keyboard to go faster)
I can type in speed > 42 WPM with accuracy> 90% for the first 4 lesson in TypeFaster Colemak's Lessons. In fact, I managed to reach
around 46 WPM for lesson 1 with 99% accuracy.

Note:
- During these four days, I was only using Colemak for typing and at the end of each day I tested my speed in Qwerty for only short periods of time.
- I still think that it is possible to preserve the Qwerty typing proficiency, but it will take longer timing curve to learn Colemak.
-In general, I am very pleased and content with this Layout and I will continue to use it. Of course, I would like to thank Shai and credit him for his efforts.
Finally, I wrote this thread in Colemak, so excuse me if I have made some typos here and there.
