I found an interesting quirk with Cortana speaking text msg's yesterday via Bluetooth or headphones.
She won't speak new text msg's if you have the text messaging app running front and center (aka focused). The phone will just play the new txt msg sound. In WP8.0 it would speak any new text msg's no matter what app had the focus, including the messaging app.
This really messed me up yesterday while driving. I had to wait till I got to my destination before I would take care of my new messages (I know, that's what you should do, but with the ability to speak and dictate while driving is one of the advantages of this thing).
