An USB Drive that shows

Yeah. I mean, If you ask me what's the unit of size, I'd say that although the Byte is the Unit of Size, the practical units are Kilobyte, Megabyte and even Gigabyte sometime. And we forget about the humble old metre. So, plusminus, an unkown company from russia, remembered meters and Physical Size, so now, you've this Flashbag. So, if you have full 2 GB of Data full, it's inflated like a helium baloon, while deleting all the stuff inside puffs it down like a pinprick on the baloon. So, I don't have to plug my USB disk into a Computer just to see how much space I have left inside. Cool Idea, huh ?
