I can not believe what you are saying !!!!!
You are making a big mistake. The Dvorak keyboard is the best. It is so convenient and amazing, it will change your life. You can write lengthy emails effortlessly.
I think that changing to DV in 2005 really changed my life. I can type very quickly, and have spare time.
I have started my own business doing iPhone apps in Swift and because I use Dvorak, I can work for hours, no problem. I have no clue how Qwerty people do it. It's like running a marathon with a large backpack and office shoes.
You just have to be a bit more tenacious when you start.
In my case, what I did was to switch from Qwerty to Dvorak when I finished college and I was between jobs. I used only DV for about 2 weeks. I'm telling you, after 2 weeks of DV, you will not want to switch back.
You need to do everything in DV for this period of time. I did not have a Typematrix then, I bought my first one in 2009 and I love TM. I really do. I'm using a 2030 right now.
The way I learned DV was to type groups of letters abc abc abc abc....
Once I got abc, I did def def def and so on until I could do abcdefghijklmnopqrstuvwxyz etc.
DO NOT switch back to Qwerty. Give DV a chance and trust me your life will change for the better.
PS: I could never write this kind of thing on Qwerty. Actually, I am so fast at typing, I always wait for the qwerty ppl when I chat with them...
I hope this helps. Good luck!
