So your argument is that compression doesn't exist? Do you also listen to 128kb WAV files and argue that they are equivalent to 128kb MP3s?

From a distance of about 8 feet on a TV about 50 inches in size, the difference between 720p and 1080p is visible to a person with 20/20 vision. The eye cannot perceive 720p worth of pixels at once, but in the small spot the center of a person's vision is on, pixel density matters a lot.
Let's do the arithmetic:
720p is 1280x720 pixels
RGB = 24 bits/pixel
60 frames/sec
1280x720x24x60 = 1.3 Gbps
For comparison: Full broadcast HD is around 15 Mbps
Why people think they can see full 720p worth of information is beyond me.
EDIT: Pay attention to the last sentence and the posts above. Of course I don't think people can see 1.3G worth of info.
Again: Why people think they can see full 720p worth (=1.3G) of information is beyond me.
