Remember the Watchman
For all of those folks who can’t blather enough about waiting for the "next generation" of iPod that has video or who are excited about video on cellphones or who insist on writing off today’s audio podcasts as a mere stepping stone to video in the future, I have one message: remember the Sony Watchman.
Now, that’s not to say all of these ideas are bad or that they can’t succeed. But let’s remember that portable devices lend themselves much more to audio presentations than video. After all, the whole idea of a mobile device is to allow you to be connected while moving about. Hard to walk, run, drive, bicycle or do anything else safely if you’re watching video on some device. But you can certainly listen to audio.
It’s vital to focus on the impact of innovation and not simply the innovation itself.
