Israeli here, flying to Europe couple of times/year. They don't make you turn on all electronics in Ben Gurion, that's just not true; asked me to boot up my laptop once or twice (probably because it can be used as a case for explosives due to its size), but not cellphone or an iPod.

Maybe they do check Muslims more thoroughly, that would make sense. I never took any interest in it, so cannot confirm it. (In the Army, I would totally pay much more attention to Arabs than to other civilians, but that's so painfully obvious, right?)
