The iPhone comes in 8GB and 16GB. That's a lot of capacity fill. And where do we get content enough to fill that capacity? No, not the torrentz (JAR!) -- iTunes!
5 years ago, Apple realized that if they wanted to sell iPods, they needed to give people stuff to load onto those iPods. Now, what originally began as a Mac-only 200,000 song sparkle in the eye of Steve Jobs, has grown into the cross-platform (except for Linux!), multi-billion track served (some even DRM-free!), #1 music retailer, not to mention the foundation pillar of podcasts, with nearly a gazillion free audio (including our very own Phone Different Podcast!) and video programs there for the downloading.
Happy birthday, iTunes. And here's to many more.
