An other little gadget I don’t recommend to take while traveling by plane. Security might freak on you.
Pull the plug and lob your old flash drive out your window (preferably after you’ve backed up the files, but who are we to tell you what to do?). Store your most valuable and portable files inside a grenade for maximum style points. Unleash that little evil part of yourself that wants to blow up your coworkers. That annoying guy three cubes down want the same files you’ve already emailed him 30 times? Pull the plug on your grenade and fling it into his cube. It won’t blow up, but at least a grenade to the head might make him reconsider the next time he wants to bug you about something…
