iPodGarage has an interesting essay about Apple's entry into the iPod accessories space. At first blush, it seems that Apple is trying to grab a piece of a lucrative pie by nudging out other players in the market. However, this would be suicide. Those same players would just go and congregate around any number of less-popular MP3 players, leading to a lonely life for Steve and the iPod designers.
The real reason, iPodGarage posits, is that Apple wants to make the millions of iPod users out there aware of the aftermarket accessory world. This is a bit dubious to me, but it sounds logical. After all, the more crap you buy for your iPod, the better the chance you'll buy the next generation gear. What say ye all?
