I was pretty excited when it came out, and it was fun, but in the end it's not useful. My issue is that while it's very good at comprehension, it still makes too many mistakes, and those mistakes are cumbersome to correct. As an example, my writing sometimes contain unusual names, technical terms, or abbreviations, and the only way to correct is then to get the keyboard back and type them out. In the end it would have been easier to write everything with the on-screen keyboard.
