We read all of this, yesterday we flew back to Kef through Manchester airport, you have to show all electronic devices,ie laptops netbooks clever phones etc. they go onto a tray and go through the scanner, if you have a fancy poser type of watch, the same applies. We were not asked to power up any devices. Our phones, quaint types that simply talk to people or text people that live on earth, were left in pockets. All types of phones that Pi$$ people off in a Taverna had to be put in a tray.
In short the checkin only took 20 minutes, no probs, last month Manchester checkin took 2 hours!
in other words a far better experience.
