Are they going to come up with a different swab test for electronics? The ones they use for people have false alarms way too often. If a piece of electronics does alarm, what happens next, shut down the checkpoint, evacuate the terminal every time this happens?
The whole 1+1 idea is going to be confusing. What will constitute one piece? I can totally see one airport allowing a laptop, power brick, mouse, and external hard drive and then another airport denying the hard drive or the mouse.
