> typing blind on a keyboard I am not used to is anyway a hopeless endeavor.
Sounds like you’re a special case then. Most people can type fine on any qwerty keyboard. And your willingness to turn a blind eye to pretty major annoyances makes it seem like you’re trying to justify the effort you’ve put into Colemak. Even if you aren’t doing that, you’ll get more mileage out of just admitting that it’s annoying to have to use another keyboard.
