What if you show up to the airport today with your laptop? I would not check a bag with my laptop in it for either love or money. I would turn around and cancel my trip. Would they let me put that in my plastic bag with my wallet and passport?
UPDATE: I switched on MSNBC a few minutes ago, and they are now interviewing a Congressman who says that UK officials are not allowing on cell phones or laptops because they are concerned about the ability to use them for detonation.
