Interesting idea.

I always chuckle when they ask you to turn on your pilot and your cell phone. In Hartsfield signs ask you to put your cell phone in your carry-on to save time. It shows how ridiculous it all is...either a cellphone is a danger or it's not. If it is, then they should check them religiously, if it's not, why check them at all?

I've taken my PC through security and probably once in 25 times they "sniff" the bag. The rest of the time I'm never asked anything or delayed. It is rare that they check. It seems that about 2 years ago they used to check laptops a lot more than they do now. I travel with people who get theirs checked out a lot more than mine. Go figure.
