I am a huge movie buff. Not into music at all(have a maximum of 1 Gig worth of music in all my life to date). I know that I-pad and movies don't really go hand in hand but I do want to have at least two films on my I-pad. One is Avatar and the other is Chinatown. I checked the I-tunes site and it costs about 10 dollars to buy a film. Before purchasing I wanted to clear a few doubts: 1.) How is the clarity? Is it HD- crisp clear? 2.)Is it worth it to buy from I-tunes considering I will be buying only 2 titles?
