i watched a guy do this catty corner/across the aisle from me on a flight a few days ago. his blackberry was ON (blinking light) and he was scrolling, typing, etc. as we started take-off. again, without getting into whether or not it's really dangerous, those are the rules, dude. i didn't do anything other than stare--like the op, fa's were strapped into jump seats already so couldn't see him--and he did eventually put the damn thing in his pocket as we took off...but clearly, he didn't feel the rules applied to him, and that's the kind of thing that drives me bananas.

i contemplated saying something after the fact to the fa, but that seemed like a page from a kindergarten handbook (see: tattling) so other than shoot him dirty looks from time to time, i did nothing. if he'd been sitting next to me, or even directly across i might have said something, but i was in 3a and he was in 2b, so it would have been really awkward. just annoys me how some folks feel they're sooo special.
