This article suggests an approach Apple could use to secure the dominance of its iPod and the AAC music format the iTunes Music Store uses. The article itself is interesting, but the comments are more interesting (and less naive, in my opinion). I’ve been following this particular situation because I’m a bit of a Mac dork (if you hadn’t guessed), but also because this is the first time in a long time that Apple has had a successful product dominating any market and I’m curious to see how they handle it.
