Your lock choice should mesh with the location where you need to lock your bike. I park my bike in two places: at home and at work. At home I leave it unlocked in the carport. At work I use a cable lock, since it's inside a gated parking lot with multiple cameras. If it were stolen, the guards would easily be able to review the tape, see the thief cutting the cable, and get a description.
I thought I'd add this so that not everyone thinks they need $100-150 worth of locks. On campus, yes, you want your bike to either be uglier than the rest, or secured better than the rest. Given a choice people steal either the most desirable bike or the easiest one to take.
