The recent wave of ultra-thin USB drives continues with the KeyXpress, a key shaped USB flash drive by Aexea. This is actually a pretty cool concept, since you can easily lug around a good number on a keyring and mix them in with your other keys.
The KeyXpress has a 4GB storage capacity and is available in black, green or light blue. What's really interesting is that this USB drive only weighs 2g, which is extremely light. The Aexea KeyXpress Flash Drive is available for $27 at the USB Brando website.
