Hmm, is it worth it? Maybe? It looks pretty darn thin and very key-chain compatible.
“It’s shaped like a key, thin like a key, sturdy like a key and goes on our-you guessed it-key chain. It’s got all the bells and whistles you’d imagine (Hi-Speed USB 2.0, works on a Mac and PC, 8GB of storage space, ReadyBoost compatible) but it’s the fact that it’s so thin, so rugged and water and scratch proof, that makes it special! No more worrying whether something might happen to it, done, forget about that, this one is built to last.”
