Progress

Tweet [1]

In 1979, Sony introduced the Walkman [2], the first portable music player. It weighed 14 ounces and cost $200. It could play a cassette that could hold about 90 minutes of music. It was a little bigger than a cassette. It was pretty ugly.

A new nano from Apple was announced yesterday. It weighs less than an ounce. The 8GB model is $149. It holds about 60 hours of music. It is smaller than a matchbook. It is very beautiful.

So it is cheaper (even without accounting for inflation), weighs 1/15th as much, and holds about 40 times more music of higher quality. I can’t get over how beautiful it is [3].
