Unlike on-line data thieves who can automate their data collection to attack thousands, actually retrieving data from you stolen laptop will take significant human effort on their part. If there were bootable CDs out there that they could use to scan a laptop for information to sell that might change things, but for now I suspect that even a low bar would be sufficient to deter random thieves from bothering to retrieve you data. There is also the value of their time. If your info is really only worth a $1 to them vs ?? amount of time; are they going to bother? Of course, even though it might only be worth $1 to them, it might be worth much more to you to reduce the aggravation. How much time it will take you and whether you should be willing to spend that time (as insurance) against future loss isn't obvious to me. It seems like whenever people start talking about computer security, there is a tendency to shoot for the maximum theoretically possible. We don't do that when it comes to our cars or homes, but it does with computers.
