Ah, right. I misunderstood. And my short-term memory is so bad that I can't actually remember what I misunderstood. Jesus.
I reckon touch-typers are a minority, by the way. Freaks, the lot of you.
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 :((
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.
