I threw some of them in my preorder basket since I get a 25% disc on accessories, figured they would be fun to play with but i haven't really thought of any killer uses yet. Any ideas out there? A tag on my desk at work for "work mode" seems like a good idea (wifi on, ringers off, etc) and one in the car (until i get a car mount), that turns wifi off, makes the ringer super loud, and starts google maps. I am too lazy to fiddle with my phone on a regular basis like that, so the tags might be a decent way to better leverage all the settings i normally ignore.
