Wired’s Joe Brown tests the SPOT Satellite GPS Messenger the only way he can: by getting lost. After eight hours of doing his best to get lost in Tahoe National Forest, he pressed the SOS button; help arrived in 30 minutes. This was planned in advance with SPOT and the relevant authorities, but this is not the sort of service you play around with casually, so I suspect that this is about as close as you can get to a real test as you can get. Lord knows emergency services get too many false alarms as it is. Via Gadling and Gizmodo.
