David Pogue at the New York Times wrote this week about a new, novel use for cellphones: tracking your children. Several new ventures, including ones from names like Disney, Verizon, and Sprint, will offer web-accessible locating services by pinpointing the G.P.S. signal in their commercial devices. There's also some discussion of child-specific services, like the 'Whereifone', which is more 'Star Trek communicator' than actual cell. From the article: "To pinpoint the phone's location, you call up the Web site, enter your password, click 'locate,' and presto: an icon appears on a map -- either a street map or actual satellite photo. In the photo view, you can zoom in enough to see individual buildings. These are existing satellite photos --you won't actually see your child standing there -- but this feature is still creepy and awesome. You can even watch 'bread crumbs' appear on the map as the phone moves around (cost: one talk-time minute apiece). That could be helpful if you're trying to assist someone lost on the road, or in the kinds of emergencies encountered primarily in your nightmares."
