I dunno, do you remember first learning to touch type? For all we talk about typing in keystrokes at a time, that's an exercise in frustration if you don't confidently know where each key is. 99.9% of your typing will be "real world" practice, but there's also utility in isolated drills.

Anyway, as someone who's tried to learn to type on prototype hardware without a working backspace, I appreciate the feature :)
