For consumers, the two big user-facing features are iOS 7 device syncing and iTunes Radio, which is nice but still a work in progress. In fact, iTunes Radios most appealing feature is simply that it’s integrated into iTunes and iOS 7, potentially making it the default streaming audio solution for hundreds of millions of users.

Bye bye, Pandora and Spotify? Those two services are certainly shaking in their boots — iTunes has killed off scores of competing music stores and Apple has proven ability to disrupt markets.

That said, go get iTunes 11.1 and iOS 7…
