The iPod competitors are all so focused on music file formats, and music delivery formats, and subscription vs. buying that they forgot about getting people who aren’t online music services to build toys for their stuff. So now, Apple has one primary interface, and three four case designs. They have a developer program that gets you information on the iPod. As of iTunes 5, the iPod integrates with Outlook. The iPod’s no longer a player, it’s a platform. The others? Just players. In truth, they’re nothing but accessories for Microsoft’s Windows Media platform. That’s why each one is an endpoint, and the iPod is really just a starting point.
