OK. I was going to say NEVER EVER check-in your electronics. I always hand-carry my laptop, MP3 player etc. Luggage should always be clothes. IF you lose your luggage, they’re just clothes and can easily be replaced. Laptops or I-Pad with private info on them cannot.
Even then, how do you keep your equipment in sight? They pull you aside for a hand pat down and your hand carry goes on out of sight.
