Several services are already offering synchronized viewing across devices. Netflix (NASDAQ:NFLX), YouTube, and now Apple (NASDAQ:AAPL) all offer bookmarking -- start a show on one device, pick up where you left off on another. HBO is a rare exception because of its cable ties.

It doesn't have to be this way.

This sort of arrangement is central to Apple's TV strategy: enable the widest arrangement of content anywhere via iTunes and aggregated services, and then sell a ton of devices to users who want access. Tim says to expect it to pay off.
