The Tomato external hard drive packs a lot into its tiny and attractive package. Its 60 gigabites of storage and brushed aluminum case all fit into a casing smaller than .3 inches. And, since they are so small and attractive you could hide these (or display them) almost anywhere.
It runs around $100, but unfortunately, we have yet to find a US distributor for this Korean design. You can see more photos over on its product site (in Korean.)
