Macbook Pros used to have brushed non-glare screens... and now the "Retina" has glare again. Why?
From what I've seen and heard, the modern glare screens Apple uses on the Retina models has less glare than the predecessors.
However, I see Retina-quality screens from a few other manufacturers, and those are offered in non-glare variants.
A friend of mine has a 2011 or so MacBook Pro with a brushed/matte screen and it undeniably has less glare than the Retina screens. In fact it almost has no glare at all. No idea why Apple discontinued that.
Æsthetic preference?
I believe color reproduction is better on the glossy screens.
