@The Apple,
First of all I want to say. You guys are a tough crowd. Secondly if you put out a quality product with quality support (which Apple does both). Why would you be so worried about customers jumping ship just because you open your media store to outsiders? I think it's safe to say once you buy an Apple product. You are hooked for life if you can continue to afford their products. Any other device that can integrate with Apple is a win, win for Apple. Apple first makes profits from additional sales. Apple also by letting in outsiders exposes outsiders to the world of Apple.
Since no one liked my other analogies let me throw this one out there. Apple is playing the proprietary game and enjoys it. Why is there a version of iTunes for Windows then? Why not just make iTunes exclusive to Macs? We all know the answer to that one, market share. Okay so Apple will dance with the major players but stomp on the little guys.
Do you think a die hard Windows person is going to dump their Zune for an iPod, maybe after using iTunes. Windows media player is no where close to iTunes. Now the same question but different. Do you think an Apple loyalist (Fanboy/girl) is going to dump their iPod for a Zune, heck no (I know I'm not). Apple could gain new customers through conversion if they would just open iTunes up a bit.
So all of you don't mind a Windows version of iTunes. Yet you believe that the Pre should not be able to integrate. Makes no sense to me...
