I'm just going to stick a spanner in this...

Earlier this year I had my XBox 360 stolen. Last month I got a call from Microsoft saying someone had tried to re-register it on Live. I passed this on to the police and the police and Microsoft started talking to each other. Unfortunately, in the words of a MS support person I spoke to "we've never had anyone stupid enough to turn on a stolen XBox before" and neither them nor the police had a clue what to do.

It's all very interesting making your N800 tell you it's been turned on after it's been stolen... it might even be interesting taking a photo of the person operating it. But you'll probably only end up with a picture of the poor sod who bought it cheap from a 2nd hand pawn shop, not the person who stole it.

Also... so you're giving the new 'owner' of my N800 SSH access to my PC? That doesn't seem so wise.

And I can say from personal experience, it's damn frustrating knowing that your stolen property is being used *right now* by someone who shouldn't have it, and you're powerless to do a thing about it. It's actually better not knowing.

The GPS wouldn't be a workable solution either... have you seen how long it takes to get a lock outdoors? "I think I might be stolen. Please stand still for 20 minutes while I get a lock on your location, thanks"... not going to happen.
