I'm glad they are going to implement seating and have always thought how stupid it is not to have it. It was Steve Jobs' Apple not listening to the customer and thinking more about cost per square foot to cram as many people in as possible.
I'm a lossless audio guy, and you are not going to notice the difference between an MP3 and lossless audio file unless you have top quality headphones/speakers. If you have those then you will notice a huge difference.
I was in Chicago visiting my family for Christmas. I rented an HD movie from the iTunes store and it took over an hour just to buffer it. Turns out my uncle only had 3mb down and 1 up. Paltry! At that rate the movie would have kept buffering.
