Google.com/dashboard is a central place where you can manage and monitor all of the data that Google collects from you through its services. One of these services is Location History, and you can actually see all of the places you've visited here.

Dave wants to find an Android alternative for the "Find My iPhone" app. Leo says that LookOut is a good option. It scans all downloads to make sure they aren't problematic, but it'll also tell him where his phone is. He can even remote wipe the phone if he needs to.
Lookout also has a feature called "Signal Flare," which saves the last known location to LookOut's cloud servers should the battery die or signal stop.
If he has a Galaxy SIII or above, his OS has this capability natively.
Chris says there's a myth out there that you have be at a great location to get a great picture. Nonsense. Location doens't guarantee great pictures, just different ones. Leo says it doesn't really guarantee to have a great image with a great camera. You can have lousy eye and get lousy pictures just as much with a 5D Mk. II than you can with an iPhone. And you can get a great shot with an iPhone as well. Chris agrees. The key is practicing. Getting really good with your camera and seeing a picture before you take it.
There's a free open source program called Prey that Robert can try. This software will run on the laptop and use wifi access spots to "phone home" from time to time. It can lock data and even remote wipe it if necessary. If that doesn't work, then there's always Lojack for Laptops for $40 a year, or Orbicule for Mac.
If Bruce gets a GSM phone and a local data plan in Belgium, then everything should work just as it would in the States. The Google maps or Open Street Maps that most services like Instamapper use both have excellent maps for Belgium. The biggest concern here is really the cost.
Another possible solution is the SPOT Satellite GPS Messenger.
