I use it exclusively (except passwords and other fields w/ no microphone symbol). I've learned to speak kinda robotically and it recognizes 95% + of my words and punctuations. Don't even use Swype any more and I used to be a fanatic. The wife said she's not that excited about it for the Eris update and said, "I don't want anyone listening and seeing me talk into my phone." I just replied, "DUH" and she laughed.
