Sure, a gps track and pictures of the thief would be great (although with current GPS first fix problems, I am not so sure...). But I am just pointing out what can already be done without efforts. For saved passwords: I suggest "password safe".

About the police: you mean that they will go after a kid who exchanged a few movies on eMule on the basis of his i.p. and not after someone who stole a 400$ tablet? I am sure that the press will be delighted to report that if it ever happens...
