Sure it's a preference thing. Some people like glossy, others like matte. To each their own. That's also why comments like "just buy glossy and shut up" are troublesome and annoying.
I have just found a buyer for my iMac and will get a low end 2010 Mac Pro. Personally I can't stand the mirror screens. Turning up the brightness doesn't help if I'm working on a design project with a black background or if I'm running through a dark dungeon in some kind of game. Then there is the issue of dust and smudges behind the glass that many iMacs develop. No thanks. I'm sure the Mac Pro will last me for years to come and I know I won't buy one of Apples glassy screen products again. (this includes iPhone and iPad, but not because of the screen, but because I have no use for them ;-)
