Apple's decision to stream its event live is actually a cover for a test of eventual iTunes streaming, a rumor asserted today. The first-ever Apple stream in eight years is reported by Apple contacts to be a practice run for the North Carolina data center to see how well it copes with a heavy traffic load streaming to iOS devices. Cult of Mac speculates that the Maiden-based facility might be used for 99-cent iTunes TV rentals that would be unveiled at today's event.
