Before I purchase the apple tv, looking for others who have a rear projection tv and using the apple tv. Mine is a sony 50 inch I purchased last year. Is the quality good? I have HDMI ports on it so it should be good quality but want to hear form others. ALSO, that 40gb hard drive seems very small. I see the apple tv has a USB port. Can I hook up an external drive to expand it. There is to big of a price difference between the 40 and 160 version. Thanks.
