Watching children try to figure out old technology is quite entertaining, and this video of kids reacting to Walkmans does not dissappoint.  They were big, bulky and heavy.  You had to rewind and fast forward tapes, and you had to flip tapes over, but the Walkman was your best option to take your music on the go.  It's funny to think that these kids probably know how to open a garage door with a cell phone, but they can't figure out how a portable cassette player works.
