I'm leaving for vacation 2 weeks from Sunday. First time flying since 9/11 and first time taking anything more valuable than a cheap portable CD player with me in my carryon. My iBook and iPod will be going with me. So will there be any issues with security? Will the X-Ray machine or metal detector screw up anything on my iBook or iPod? Also, since I'm in coach and I dont believe power jacks are available (nor do I have a cigarette lighter adapter), do you guys think my iBook battery will last the full flight from St. Louis to NY-Laguardia (nonstop) while watching a DVD or something? Thanks.
