So, Apple used to ship the matte screen as standard, and upsold the glossy one as "movies! colours!". Then they shipped the glossy screen as standard, and upsold the matte one as "no glare!"...
We're the odd folks out in wanting the matte screens.
Glossy looks way better in stores (especially since Apple controls the lighting to make glare incredibly unlikely) and in pretty much any case where you do not have direct light. It's what the public wants.
