Is laptop tracking software worthwhile?

The recent publicity over This Guy Has My MacBook has gotten me wondering.

I mean, it’s a great tool, if you need it. But my main concerns are the subscription model and, as mentioned in the article in passing, the privacy implications of giving someone who is basically a stranger access to your webcam and maybe HD.

Thoughts?

I don’t know how it compares, though.

Yes, it’s worth it because if your laptop ever does get stolen, we can be entertained by your story of how it was recovered. With pictures.
