Not sure he calculated the costs and probability of the cold boot attack quite right - I think the fact that over 40% of folks do not shut down their laptops while travelling makes this a higer probability. (This number came from a short survey we did in Pittsburgh with around 200 respondents - will provide more details in a forthcoming blog). Now cosider the fact that people think this can be done - this changes behaviour of thieves, methinks.

However, the general idea that Charlie has is spot on - the peace of mind, staying away from the headlines, the lowering of probability is what securing data is all about....
