Dang, I was looking forward to putting tags in my apartment and at my workplace. I would love to come home, tap a tag, automatically checkin / share on Foursquare, turn off bluetooth, turn on wifi etc. And next to the bed, tap a tag to put it in silent mode and ideally start playing my Squeezebox (I know, that would be stretching it a bit, but a man can dream =) I was really hoping you'd be able to build macros that would be executed.
@mopius: If you could do somekind of app that would let us do at least a tiny bit of above, I'd be a happy camper.
