After using it for about a week, I will need to travel with my parents to New York over the holidays. Since I've got to do 3 major essays and 1 powerpoint presentation, i thought i might as well bring the powerbook along. the only problem is: i'm leaving on friday, and i don't have time now (neither do my parents) to go out and get a case for the pb. I've got two cases that will fit 15" inch, but it won't do on the 17" (sooooo close!). this is a really strange question, but I do I bring it on the flight (JetBlue SAN-JFK) without it getting scratched or damaged en route? Do I carry it through security? while in the airport, put it in an empty backpack????.... please. thanks.
