There are already many key shaped USB drives around, with the latest one coming from Gadget4all in the shape of the Key USB Drive. The Key USB Drive comes in a variety of colours (red, purple, blue, brown and black), it measures 57 x 24 x 2mm and weighs a tiny 1g.

It can store up to 4GB and it is designed to be stored on your key chain, so if you loose it, then your car might be missing too.

the Key USB Drive is available for $22 from Gadget4all.
