$300 shoes contain GPS tracker in heel families can monitor

GPS is utterly useless for finding your wife or kids (or even locating yourself) at the mall. What we need is an indoor equivalent of GPS

With the rise of GPS-enabled touchscreen phones like the iPhone, you'd think that the future for stand-alone GPS makers looks bleak. Except that these companies are being surprisingly agile, and are embracing smartphones to make the best GPS navigators ever.

With TetherGPS, "getting lost in a book" will never mean the same thing again. A new app on the Android Market could turn your Nook Color into a GPS unit. TetherGPS is a newly launched app (it runs $2.99, but there's a free "lite" version) that turns devices you thought were condemned to a nomadic, GPS-less existence into street-smart, location-aware tablets.
