It's a sunny day in Seattle. The first day of your business trip is going well. You're in town for a conference, but have some time to wander. As you walk in and out of shops, your stomach begins to rumble. Coincidentally, your mobile phone rings, alerting you to a nearby five-star Indian restaurant (it knows your favorites), complete with directions. They prepare wonderful tandori chicken, so you tell your mobile phone to make a note of the restaurant.
