Has anyone seen any rumblings about the possibility of a TSA checkpoint-friendly backpack? I've finally got the bf convinced that Tom Bihn has no rival. (No, I don't know why it took longer than a few minutes for him to see the light.) He loves the idea of the Checkpoint Flyer but won't give up his backpack. Apparently Tumi has a checkpoint friendly backpack that he's considering, but he'd rather go with Tom Bihn.
