I get music and video with comcast. With it I get better sound and picture quality. I also have yahoo music. In addition I can share the experience with others.
Imagine, iTunes isn't just music but video, tv and movies. If you could subscribe to iTunes like Rhapsody, why would you need cable tv?
It could make iPhones look like yesterday's trash. If there's anything more hated than cell phones--yet ubiquitous in use--it's cable tv.

P.S. Then again, while Apple has the entertainment contacts, Microsoft, Yahoo or even Google could set up similar online structures.
