cooldude: I am aware theft is an issue with B&O equipment, but will happen pin coded or not !!!
Perhaps, one could put one more obstacle in front of an (uninformed) thief by placing a sign on your B&O saying 'Don't bother to take this with you: it's heavy, its ownership registered and has a PIN code protection system - if you don't believe try to switch it on (the remote is on the coffee table)'.
Then again, the frustrated thief might smash it on the spot or return another day to put a gun on your forhead and ask for for the PIN - depending on your neighborhood's specifics ...
Edit: Almost everyboby has internet on his mobile so the sign I mentioned could include the link to this (vikinger's) thread on Beoworld, too.
