This thing has been amazing so far.. the only little quirk that I've managed to find is when using the Voice Search app. Now, you can use this thing to do more than just search, but I get FCs specifically when I try to speak a text msg to someone. It'll recognize the command and show the dialog box with the addressee and the text, but once I hit the button to add more, it FCs.. repeatedly. Doesn't matter what the variation in actions is, it FCs every time..
Granted, it isn't an option I use too often, but just thought I'd bring it up as something to look into as you work on 1.7..
