I get an email if the weather shows it'll rain tomorrow. That's kinda nice. Also, anything I star on Google Reader saves to Instapaper, but that wont' be useful very much longer.
I wonder about other things that are nice to have an ambient awareness of. It can't be too many things, otherwise you risk overwhelming yourself with notifications / beeps / things to check / glowing orbs, but I bet we all have a bit of room for more of that.
