Keep it small with the Pico USB Flash Drive from ThinkGeek . This tiny USB Flash Drive is so small, it is a wee bit larger than your pinky while measuring less than 4mm Thin. It comes with a polished chrome finish, but despite the impossibly small form factor , you get a whopping 8GB of storage space within! That equals to approximately “four full length ripped movies , five days worth of music , more than Four Thousand 5 Megapixel photos, or eighty-meters worth of shelved books.” Good thing this $49.99 purchase comes with a chain so that you won’t it that easily. It would be nice to see some sort of password protection built-in, but I guess that can always be thrown in in the next iteration.
