It's hard to keep in mind, but the majority of buyers, and therefore the majority of income, may not be like you.
In the consumer's mind, there is no better quality than HD because it doesn't exist. Look at the way marketing speaks to the average consumer. In marketing, perception is reality.
You may know what 1080p means, but most consumers have no clue what the '1080' or the 'p' means, or how it relates to their viewing experience.
That's bullshit.
> For the average consumer (not a gamer, not a power user), the ultimate visual experience is an HD movie.
You get the same ultimate experience with the previous 16/10 resolution for this size: 1920*1200. Oh look, even more pixels.
> so the most sensible thing for a hardware provider is to deliver 1080p at the cheapest point possible.
Right, it has nothing whatsoever to do with consumers, it's just hardware providers lowering their costs by using TV resolutions on computer screens.
> Or to improve on other areas than purely pixel count (colour accuracy, brightness, viewing angle...)
Which definitely is not happening.
