I can understand the motivation, but it's definitely going to take a lot longer to get through security if I have to prove that my cellphone, iPod, PDA, Gameboy, small digital camera and large digital camera all are actually what they claim to be. I'm also not too crazy about the idea of checking anything of any significant value these days when it's going to possibly be searched out of my view by poorly supervised questionably trustworthy people.
Even less fun if I ever manage to get a laptop again (current rumors say later this month, much like the rumors have been saying for several months now.)
