A big misnomer, that has been going on for years, is the TV industry calling anything less than 1920x1080p as '720p', while they have been using various resolutions.
Anyway, at a typical distances for a 42" plasma, some of us see the pixel structure on 1024x768p plasma, so that why I decided not to buy one. For me, a 42" plasma would have to be 1368x768p to consider it, but there are none anymore.
I'll echo what others have said, it depends on the viewing distance.
I believe I remember reading an article on this somewhere else. From what I remember, the eye can notice differences in vertical resolution much easier vs. noticing horizontal resolution. Meaning the eye has trouble finding a distinguishable difference between the horizontal 1366, 1280, or 1024 lines of resolution of individual 720p sets. Whereas the eye can more easily notice difference between the (vertical resolution) of a ____ x 720 signal to that of a ____ X 1080p signal.
However, if you consider that most people and sites are saying you can't tell true detail differences between a quality 720p set vs. a 1080p set (vertical resolutions), you would most certainly not expect people to notice differences in the horizontal resolutions of those respective 720p sets.
In fact, I believe most newer sets are now 768p technically. If the eye can distinguish this vertical resolution better, than newer "720p" sets have actually increased in terms of detail resolution.
I think they also pointed out a counter argument that newer 720p plasmas aren't a true 16:9 ratio, but then explained that 16:9 ratio in terms of HD television is not related to pixel structure, but to overall TV ratio..... and that the eye cannot distinguish a 16:9 TV panel of square pixels vs. a 16:9 panel of not-so-square pixels.
