Wow -- We're going to rely on the judgment of newly-badged TSO's judgements concerning what exactly is a "full-sized DVD player."
I like the idea of everyone playing dumb and taking out everything they have that's electronic, placing each one into a bin, and grinding the checkpoint to a halt. For me, that would mean, in addition to everything posters have already mentioned, my electric razor and my electric toothbrush.
By playing dumb, we could really have a lot of fun with this.
Way to go, Kippie.
