i saw these today on boingboing gadgets, and they are my new most wanted gadget! named (left to right) iamakey, itsakey and passkey, they are available for about £20 for 4gb and a bit more for 8gb. my favourite is the one on the left (also below).
designed by french studio 5.5 designers, with a sturdy metal design that will fit onto any keyring, they are also water and scratch resistant.
