The location traces that can be easily extracted from my iPhone backup certainly *are* impressive -- I sort of hadn't expected to carry around a rather detailed trace of my movements over the last 9-12 months.  "Creepy" is the most friendly word that comes to mind for this feature.

(FWIW, I play around with foursquare, I geotag photos, I archive GPS traces of hikes and runs, and I routinely use many location-based services...)
