Typing on a mobile display is completely different to typing on a proper keyboard. Even when you're looking at the phone and can see where your fingers are pressing (or at least where you think they are which is a little different to where your eyes tell you half the time) it's too easy to make mistakes.

I can't really see this helping unless pressing each bump registers a particular key so it could make it more accurate but it's not the tactile feel where your fingers are, press the key, kind of thing.

I don't really touch type :((

Sort of half-and-half :((

Yeah, I agree.

I had to learn how in college. Glad I did but at the time I hated it. I had typed myself into a pretty good self style for years before, and having to undo those years was a pure bitch. But now I type like Doogie Houser so all's good.
