Just hit the "Picture" button again and it will toggle
back to the Activity mode. Same with the "Sound" button.
Yup, they work the same as if you're in an Activity, click Device and change over for a bit, and then hit Device two times to get back to your current Activity.
I had a 550 and went with the 670 because of the great button layout. Perfect for Tivo/PVRs. I like the peanut design, too.
