It does more than date the post. Its the most perfect example I've found of how Apple sneaks up on markets and changes things. Is there anyone left who might think that a cd walkman and a burner are somehow equivalent to an iPod? Nobody called him out though. In 2001, it seemed reasonable.
I can't help but compare this to the "why do I want an iPad? I've already got a laptop and a smartphone" crowd. I was underwhelmed by the iPad as well. I found myself saying "all this hype for this!?" I probably won't be buying one.
Its going to change the way humans use computers forever.
