I'd like to hear from people who have had bicycles stolen due
to the failure of their "high-security" (Citadel/ Kryptonite type)
lock, and not the "immovable object" your bike was locked to.
I'm not sure whether the Kryptonite/Citadel story is hype, and
I'd like to find out. It certainly appears it would be harder to use
bolt-cutters on one of these than a chain or cable, but I have a hard
time believing they're only succeptable to "200 lbs of cutting/welding
equipment", as some of the advertising suggests.
I've been told (by my local bicycle "entrepreneurs") that a
Kryptonite lock can be shattered by applying dry ice [did I just
encourage some would be bicycle thief?]. Does this only apply to the
dark colored ones on sunny days (i.e. temperature difference), or is
it a general characteristic of "hardened steel"?
My local bike shops swear by the Kryptonite locks, but I've
known people who think the Citadel is the only one worth using. Are
these profit/religion motivated people, or is there some fact behind
their opinions?
General comments on bicycle (and "fixed" accessory) theft
prevention are welcomed. (Using typical outdoor bicycle racks or
typical city immovable object -- indoor/controlled environment makes
the problem less difficult.)
I will post a summary.

I've heard tales that a Kryptonite can be broken using liquid nitrogen, which
is much more believable than dry ice. No proof for this, though.
My last lock wasn't a Kryptonite, and I regret it.

A 20 lb. bike needs a 30 lb. lock, a 30 lb. bike needs a 20 lb lock, etc. My solution is to keep my bike in my office, the lock is for real emergencies when I CAN'T talk the bike indoors.
