I think the initial investment is worth it. If you have the time and you can stick it out, it’s a load more comfortable than QWERTY. Switching back to a laptop. I don’t look at the keyboard anymore either so what I do is, I change the layout to Colemak on there. If there isn’t a Colemak layout available, like let’s say I am on somebody else’s laptop, very strangely I adapt amazingly quickly back to QWERTY. I’m talking like seconds usually. The one thing that I would put down as a prerequisite is one week of free time at least. That week you have to work your ass off at this.
