Today, while cruising my favorite blog, I found out about an amazing piece of technology. A 1GB USB thumb drive that is smaller than your thumb!
This thumb drive is made by OCZ Technology and is amazing due to it's size alone!
Because the plug folds into the main housing of the unit it is able to be as small as a USB plug! I have not tried opening one up yet but I imagine the housing is only there for protective purposes. All of the "guts" must be in the plug itself or else you would risk damage from continually opening and closing the device.
