"The size of the [USB key] device changes depending on the amount of data it holds. When the device is about to blow up you will see the familiar error message on your screen: "There is not enough free space". When swithched off the flashbag remains pumped up, so you can estimate with the naked eye how much more pics, books and music albums can be transferred into it".

"Just plug the Wireless Extension Cord (WEC) base unit into a standard wall outlet, and plug whatever you need into the satellite unit. The WEC uses microwaves in the 7.2GHz range, so it won't interfere with wireless networks, Bluetooth components, etc."
