I am really most interested in the perimeter sensor, helps to keep the morons from climbing all over your bike while you are out of sight.
A friend of mine walked out of a store just in time to see a kid climb onto and knock over his new bike, while the parents stood by and watched. They probably werent too happy when their insurance coughed up $7000 for repairs.
