Flashbag: The inflating USB flash drive
This product is only at the concept stage, so you can't buy it. But, it's a standard USB drive that has a tiny pump in it that inflates when you load it with data. So if your drive is full of stuff, it blows up like a balloon, but if it's empty it remains flat and rectangular.
Sounds like some concept allright. But, we can't think of anyone who would want something like this. Would you carry a full size mango in your pocket? No, then why would you carry this, aye?
The Flashbag is one hell of concept, but it's not what we will ever want to carry ... ever! Of course, if you really want to know when you drives are full pick up a drive with an LCD display. Trust us, that's going to less embarassing. :)
