I just took delivery of the sweetest little hard drive. I'll use it to fulfill my New Year's resolution of having a complete backup of my hard drive so that if my laptop's hard drive crashes or is otherwise vaporized, I'll have a complete backup, ready to go on a new machine.
The drive is one of the nicest, highest quality drives I've seen, encased in that ThinkPad black rubber material, with a keypad to provide secure access. No power cord required; USB cable slots nicely into the side of the case when not in use. Slightly larger footprint than a deck of cards and less thick.
The drive is this one from Lenovo, profiled on the Lenovo design blog here: LINK.
