The sheer brilliance of it.
But when I purchase my Rebel XS(i) I will simply never let it detach from my person at any point at any given time. Finding small locks for traveling bags would also be in order..

Anyways, unless you are one hell of a lucky person you will lose, or be the victim of theft at one point during your travels. Simple fact. Just don't freak out (unless it's your wallet) and have back-up.
