Each time there’s a security incident affecting air travel, it becomes harder to get electronics through airport security. Last week’s terrorism alert, for instance, raises the possibility that laptops, video projectors, and DVD players — devices big enough to conceal a couple pounds of explosives — will soon be banned from carry-on luggage. There’s further speculation that any computing device capable of serving as a timer or detonator — which includes cell phones, iPods, basically anything with a battery — may eventually be excluded as well.
So how do you carry your presentation? David DeJean discusses this on the InformationWeek site.
