On this day in 1979 Sony introduced The Walkman-which was terrific. You could now carry your music with you. Revolutionary. Over the years I had a few of them. Sony sold over 220,000,000 Walkman over the years. Sony was on top of the world back then-like Apple is today. Sony lost their edge and has gone into the tank in recent years. Times change, like a sports team that wins a championship- you have to keep working to stay on top. With the passing of Steve Jobs you have to wonder-what will Apple be doing in 5-10-20 years?
