I think I am learning it very slowly vs. people who went cold turkey.
There are a lot of experiences posted at the colemak website.
Mine is:
I tried cold turkey but I finished the first day typing in qwerty because I couldn't work that way, I typed so slowly and inneficient.
I thought it was in some way for crazy people, why on the earth I will be going to type in a different layout everybody use ? well, statistics don't lie and in the paper colemak seems superior to qwerty, also I have always been sick while finding special i18n characters I need for my native language.
So I do decided to practive colemak for about 1 hour in my free time almost every day.
I used ktouch with a new set of lectures I created for the spanish language with all the syllables that are most common and repeated at the same frecuency as they appear beginning with just a few then expanding to the whole keyboard.
I did it for about two months when I began to fell that i tend to confuse colemak with qwerty and that was the point of no return.
I switched to Colemak and I began to type nicer.
Then I face the problem when i have to work on another person computer who didn't have the colemak layout installed and that was so painful to go back to qwerty; I realize I will find this problem over and over again so I began to find a programmable keyboard that's when I found the GH website, then the story becomes larger. Now I type on the key64 keyboard and is colemak and qwerty switchable, you can find a video of me touch typing at the key64 using ktouch at
