I totally agree with you. That was just an attempt to sum up how that user probably saw it. Based on their response (before mine) I think I got it right.The thing is that petty much anywhere you hit on the keyboard it will almost always interpret it as a key press of some sort, since even if you don't hit on a key it will still guess the closest key you probably meant and type that in (at lest that's how it generally seems to work in iOS). So, that haptic feedback would be going off petty much no matter where your pressed or how exact you were as long as you pressed somewhere on the keyboard.
I'm not of the generation that can type on an iDevice without looking. I need two hands and I need to be looking at the screen. Even then half my keystrokes are deletes to fix mispelling because I hit the wrong damn key!
So, while I get this…it's certainly not how I do it!
Now give me a computer keyboard and that's a different matter! I never learned to type, but I divided the keyboard into left hand and right hand in 1980 when I was 10 and was learning to use a TRS-80. I've long ago memorized where the keys are on a physical computer keyboard.
