An electronic device that allows books from the internet to be downloaded onto a portable electronic Braille book. This device could be hand held and consist of a series of small pins that go up and down to form all the letters of the Braille alphabet. Thus blind people could also read whilst they're sitting on the train.

A wrist watch that automatically adjusts the time to what ever time zone you are in. Saves about 300 people having to fiddle with their watch every time we get off an international flight.
