Yeah, I still won't be using any other third-party keyboards even when this is out. There's just no reason to, and my 5+ years of typing on iOS has made it faster for me to type on the default keyboard than most people I've ever seen anyway.
Yeah I believe people who are really comfortable with the iOS keyboard won't be looking into any 3rd party alternatives. I also type pretty fast using the default iOS keyboard but I would like lower case letters on top and the ability to long press for numbers.
