Last few months had a few problems with my laptop at several airports. Missing flights, and even had a laptop confiscated (I was able however to pick it up a few days later). Seems lately airport security authorities are keen on laptops nowadays. Encypting data on a laptop makes it even worse. I am very weary now traveling with a laptop. In many cases I also seem to fit a certain profile. Travelling alone (and a lot), male with no check-in luggage and Middle-East stamps in my passport.
This is just a warning and also a question whether anybody else experienced this problem.
