I've heard from several different sources that the difference in image quality between 720p and 1080p is not all that dramatic. That seems odd to me since 1080p obviously has 360 more lines of resolution than 720p -- that seems like it would be pretty significant. I don't own an HDTV yet (obviously), but when I do get the money for one, I'm wondering if 720p would suffice for a 42"-46" plasma in a small bedroom. My typical viewing distance is ~ 10' or less, so would I notice much difference between 720p and 1080p? Is 1080p only more noticeable on larger TVs and/or farther distances, or is it the other way around? If it matters, the typical source material will be HDTV channels, up-scaled standard DVDs, and Blu-Ray discs.
