This is crazy. It's almost as crazy as LGW/LHR only allowing "one" carryon item for awhile. If I remember, the security staff would consider all items physically connected to be one item, but it had to be that way going through security. It's ridiculous since these items are only consolidated for purposes of boarding the aircraft or perhaps a security line and removed right after this point.

As far as electronics go, Kindles, iPads, netbooks, etc, are supposed to be able to go through inside your carryon whereas full-size laptops, bulky electronics, etc are supposed to go through separately (but can be inside a neoprene sleeve or checkpoint-friendly butterfly case). I've also been told anything with a regular hard drive needs to go through separately. Yet, I will still get yelled at if my laptop with an SSD stays in its case even though no place in the world has given my camcorder with a hard disk a second glance buried deep inside the camera bag.
