What's the best gadget of the last 50 years? The iPod? The mobile phone? The USB flash drive? The TiVo? No, no, its none of these, according to PC World magazine - the best gadget of the last 50 years is in fact the Sony Walkman.
As the magazine notes, no one had quite seen anything like the Sony Walkman when it first appeared. The battery powered blue and silver cassette player changed the social landscape, with people suddenly listening to music on the move, whilst they walked down the street or sat on the train or bus.
Its interesting to note that now, some 26 years after the Walkman appeared, Sony is updating the little device. Reincarnated as an MP3 player, the new Walkman will be available in two capacity sizes - 20GB (NW-A3000) and 6GB (NW-A1000).
