It depends on a person's vision, and their adaptive ability to notice details in objects. We don't all see the same, and we're talking about some very fine details here.
I sit 10 feet away from my 50" 1080i -capable 1366x768 resolution set (768p). I also used to sit the same distance from my 42" LCD which was full HD 1080p at 1920x1080. I can
see differences between the two, because I specifically memorized some details in a few shots, and could make comparisons based on memory. Is the difference worth the bother? It depends a lot on the person, and what you're watching.
On things like Nine Inch Nails: Beside You In Time, I found the 1080p 42" LCD seemed much more "lifelike" and detailed, as if I were there watching live. The image was much sharper, and I could see more detail in the crowd -- their fingers, phones, etc. It was shot in video, and LCD at that resolution really makes it seem lifelike. On my 768p 50" it looks more like a TV show or a movie, but it's bigger, and has a different feeling all its own. Not bad -- just different. Part of that is because of the differences in Plasma vs. LCD technology. Another part is the resolution. I prefer different aspects of both.
If I were to go with anything tomorrow, I'd try to get a 50"+ Plasma at 1080p. That would be sweet. The last 2 LCDs I owned had clouding problems and uneven blacks, which drove me absolutely insane.
If you mostly watch movies shot on film, then the difference is not worth worrying about at 50" or less. In this case, definitely go 1080i. Why? Because I found, if anything, that having a 1080p set actually increased
the detail on one thing I'd rather not see a lot of on film: GRAIN. Yes, film grain detail is more noticeable at 1080p. That extra resolution really brings out every detail in the grain. Honestly, I prefer having 1080i and not seeing all of the grain details showing all of the time. LCD's and the way they do contrast also seem to make grain pop more than a Plasma, IMHO.
If you mostly watch high-def video/sports, instead of film, then go 1080p LCD. For some reason I can't explain, there is a dramatic improvement in video compared to film when viewing 1080p over 720p or 768p. But here's the kicker: I find that standard def looks so much better on my Plasma than it did on my LCD. Strange we can't have the best of all worlds in one set (not yet).
Again, I would say that 50" is the limit at which I'd bother to change from 1080i to 1080p. I get by fine with this 768p (1366x768) 50" TV, but I sometimes wish it were a 1080p. Other times, when lots of grain is in a movie, I'm glad it's not. Does that make sense?
I don't find 1080p essential at a 10' viewing distance, but I would at 5' though. If my screen were larger than that, then I'd certainly go 1080p (but at the moment, that's some big $$$$ to do so).
