Apple needs DRM and Closed Platforms

I am a huge fan of Apple. They make great hardware as well as software, but when Steve Jobs wrote an “open letter” denouncing DRM I knew it was just a stunt. The reason Apple is doing well is because they work under closed platforms and DRM’s. Apple has created a monopoly within their own products and services.
iTunes/iPod: iTunes works exclusively with Apple products (ie iPod, iPhone). If you don’t have an iPod, then you can’t use iTunes to its full capabilities. The iTunes Store has DRM on its video and (most of its) audio files. I know Apple has added some DRM free music, but it’s just a PR stunt. If for some reason all of the major music labels went DRM free, Apple would be in serious trouble. People would no longer have to buy iPods to use the iTunes Store, which would indeed hurt iPod sales.
