It looks like this person put a lot of thought into how text editing could be improved in iOS, and the video is well-made. However, a great feature of the iOS keyboard is that if you press the wrong key, if your finger is still on the key, you can drag it over to the key you intended to use. Has he taken this into account? It would be pretty frustrating if I made an almost-typo, and instead of inputting the intended character, my cursor moved around.

The behaviour you described is specific to the iPhone. On the iPad, if you press on one key and move to another, it releases the original key and ignores the key press.

Well, I stand (somewhat) corrected!

Also if you press and hold a key, list of accented/alternative characters is opened. Anyway, OP has lovely idea, just the first trigger has to be tuned a bit. Maybe holding and dragging the space key?
