When my friends went to MCO in March, one brought his new camcorder with them which he had received it for a Christmas present and hadn't had a chance to use it before vacation....
So thinking he would have 3 hours to read the directions and learn how to use it, he took it with him on the plane... When going through security, the agent ask him to open it and turn it on so they could make sure it was "real"... well, he said " To tell you the truth, it's new and I don't even know HOW to turn it on.. She said "I can't turn it on for you, but I have one like it and can TELL you how to turn it on" Luckily, the battery was charged and working.
Thank goodness the security agent was "human" but also Thank goodness they are scrutinizing "normal" electronics more closely now!
I think it's worth the extra security
