I think we can all stop reading this nonsense after this line.. Seriously, why is it that the most uneducated people writing articles are invariably located in the USA?
It all depends on the viewing conditions ...
I watch my 32 inch TV at a distance about 8 feet away while I know people with a similar sized TV who watch it at (roughly) twice the distance. With how close I watch the TV pixelation is noticeable, at the distance other people watch their TVs at it would be difficult to tell the difference between upscaled DVD (or DVD on a CRT) and a HD format like Blu-Ray
