I type like Randy does: with the my pointer, middle, and ring fingers while staring at the virtual keyboard. And I would add another iPad typing tip: cut your fingernails.
But you know what? Even after using the iPad for a year and a half, I rarely ever type long-form on it. Yes I got the memo that the iPad is for creating and not just consuming, but in real life I mostly consume. (Speaking of which, we need a new phrase to replace “consuming content”.)
