Funny story. I started learning Colemak must have been close to a year ago now. I switched my home computer and phone to Colemak, but kept my work computer on Qwerty as I wasn't quite ready to suffer the initial productivity hit even though I knew I needed to do it in order to really breakthrough. In the end I couldn't commit, so I switched everything back. About 6 months later my wife received a text while she was driving and asked me to reply to it. I picked up her phone and fumbled through typing out a reply. Something felt off. I opened up my phone to compare. I had never switched my phone back to Qwerty and my brain had completely adjusted. So much so that I didn't even realize my keyboard had been Colemak for the last 6 months.

It's still Colemak to this day.
