EDIT:  Rereading and following your link, I think that link that you provided does offer a strong reason.  Apple places appearance including the functional part of appearance near the top of a list of requirements.  I imagine Jobs would quickly shoot down a product that would have users complaining about viewing angles and difficulty sharing the experience/use with (social / physically present) company.  And good color reproduction also fits into this requirement.<p><a href="http://en.wikipedia.org/wiki/Lcd#Drawbacks" rel="nofollow">http://en.wikipedia.org/wiki/Lcd#Drawbacks</a><p><i>LCD panels using TN tend to have a limited viewing angle relative to CRT and plasma displays. This reduces the number of people able to conveniently view the same image – laptop screens are a prime example. Usually when looking below the screen, it gets much darker; looking from above makes it look lighter. This distorts the colors and makes cheap LCD monitors unsuitable for work where color is important, such as in graphic design work, as the colors change when the eyes are moved slightly up or down, or when looking either at the top of the screen or at the bottom from a fixed position. Many displays based on thin film transistor variants such as IPS, MVA, or PVA, have much improved viewing angles; typically the color only becomes a little brighter when viewing at extreme angles, though much of the improvements on viewing angles has been done[citation needed] on lateral angles, not on vertical ones.</i>
