Actually, Netflix even has a decent number of TV shows on it. In fact, the TV selection is arguably of higher quality than their movies!

For a while Heroes (not an argument for quality ) was going up on Netflix a day behind the original air date, and even now you can stream every episode of the show through Netflix. There are dozens of other shows on there that I might try out simply because I have a Netflix subscription.

So I agree, I do think it's curious that Apple would put Netflix on there. The only other reason I can think of is that Netflix's strategy might be paying off: become ubiquitous. Having Netflix on your home theater device has almost become table stakes, so when you don't have it you stand out in a bad way.
