Cell Phone vs. Walkman

Ran across a blurb in Adweek that mentioned the following:

"Sony has sold more than 400 million Walkman-branded items worldwide since the device's introduction in 1979."

Then, I recalled the following factoid that I ran across yesterday:

"LGE, a Korean handset company, has produced a Mecca-finding handset with GPS technology in it. So it's a tool of religious devotion. They anticipated selling 300 million units in the first couple years."

I think this gets at 2 things. First, the pace of technology adoption is exponentially faster than ever. Second, there is probably no tech device that's sold faster than cell phones.
