Flashbag - Bloated and Useless

Here's a new idea from Russia with love. It's called the Flashbag and it's a usb flash drive that inflates depending on how much stuff in on it. So when you copy files to it, it gets a little bigger, when you delete files from it, it gets a little smaller. It does seem like a cool idea, but it also seems almost completely and utterly useless. I wouldn't want a USB disk that could fit in my pocket in the morning and enhance my package by 3:00. It's just one of those wierd things that you would expect to come out of Japan.

Does anyone remember the Reebok pumps?
