How would you navigate an app or browser without using you hands/fingers? Your football score scenario is already accomplished via ESPNs Score Center app. It can be configured to send notifications based on team preferences (i.e. notify of scoring plays during your fav team games).
And now that I think about it, if only the Google Maps app could be configured to send turn-by-turn notifications, we would sort of have GPS on our Gears.
oh I forgot about the turn by turn functionality - Pebbles can do this, even though I never got a chance to use it since my phone is mounted on my dashboard. Would be useful when walking in a city, though - without keeping your phone out. The problem of course is the watchscreen turns off again and you have to touch the watch and navigate to the app again to see the next direction.
