Nifty Gadget: The FlipSync USB Cable Keyring
At $20 it's not cheap but it does have a nice look to it for those emergency charging needs. I love carrying around small adapters and useful items, and if you don't want to bring a full sync and charge cable (or even a retractable) this may be a great option when you're on the go. iPod/iPhone version available as well as a Mini & Micro USB version (Most likely more to this crowd's tastes!).
