I recently got my 830 as a birthday present. I would be gutted if I lost it.
I am not totally familiar with it yet but could you not possibly track it?

Best of luck finding it. If you can't locate it, maybe we can all contribute a little bit to fund the cost of a new one for you. I would contribute!
15 or 20 kind hearted people contributing $25 each and boom! Less than a cost of a decent lunch, and far more gratifying. Count me in.
Edit: nvm. I see you are all over the "last known location" thing. But I would still be down with helping you get a new one ASAP.
