My 2c: My wife and I increased the number of discs we have at a time from Netflix shortly after remodeling the basement and doing a major upgrade to the AV system -- built around the 970, of course -- with the thought that we'd better recoup some of the expense through savings from fewer trips to the local multplex. It was a matter of financial pressure as much as anything else, but I have to say, I haven't missed the theater one bit. The experience at home is at least as good, and I get the additional thrill that it's MINE, ALL MINE!! Every time I get blown away by an image or piece of audio, I can't believe that I actually own this fantastic stuff.

As for the size, ... well, we watch our 91" projected image from a distance of around 8', so that's the same field of view as a fairly average seat in a theater. We usually sit up closer in a theater, enjoying the immersion, but frankly, the sound's not as good up there, with the front and center channels being a little too dominant, so I think we do better at home, where we're in the sweet spot for everything.
