It depends on how far you are sitting from the display. From my 30", I sit about 2 feet away, max... If I had a 37", I'd be sitting about 3 feet from it and if I had a 42", I would (do, rather - Dad's Plasma) sit about 4 feet from it. With all else being equal, pixel size doesn't matter much because once a display takes up most of your field of vision, then increasing the size means you have to increase distance from the display nearly proportionate to the size increase. In other words, all this pixel density crap, is just that, crap when talking these large displays. Pixel can be the size of a house, but so long as you are a mile away, it doesn't matter much.
