I just read your whole thread; you've really improved. It looks like you're about 20 WPM short of what you were on QWERTY. How long would you estimate it will take you to reach your QWERTY speed?
I think it's pretty reasonable to say that I'll be back up to my "normal" speed by the end of the year.
My question is (since I'm brand new): are you glad you made the switch? Would you do it all over?
Making a switch like this requires a lot of consideration of all of the pros and cons, and you can't base it just on the hope that you'll type faster on this layout versus another. I find typing with Colemak to be an overall better experience than typing with Qwerty. The common keyboard shortcuts are in the same place which is a huge benefit to me, and having to move my fingers less to type makes it an overall more comfortable typing experience. The caps lock key functioning as a Delete/Backspace key is something that I've become accustomed to.
Overall, I think the switch so far is worth it. The things that factored in to why I chose Colemak over another layout is that Colemak has an easier learning curve since most of the keys are in the same place or one key over meaning that many shortcut keys are in the same place. Dvorak isn't too great since the vowels are all on one hand meaning that you use one hand more often than the other (I think the right hand has much more action on Dvorak) whereas Colemak is pretty well balanced between the hands. I did look into Workman when I was deciding to switch, but I didn't like how many keys were in a different place ruining my cut, copy, and paste shortcuts...something I use every day for work. Sure, I could customize the shortcuts, but I wouldn't want to have to do that every time that I get a new computer.
The only thing that I don't like is that my WASD layout is different for gaming, so I have to customize each game with the movement and action keys. At the very least, I have a slight insurance policy against potential RSI issues down the road, and that potential benefit alone is worth it for me.
