I'm not sure if "anti glare" is what you would exactly call those shiny screens, but I personally don't mind them. If I move my head more than an inch in almost any direction, the colors on my PowerBook's screen "change", and this is the last rev. PowerBook before the MBPs, so it's got a decent screen (after replacement for the stupid horizontal lines...) Also, the sides and corners seem to "fade" out on this screen. Even looking at my mobile phone, which seems to have one of these shiny screens, it seems almost brighter than my PowerBook, and with no fading in the corners at all.
Those shiny screens seem to have better contrast and brightness to regular, "matte finish" LCDs. Side by side, the colors are more vibrant, and the regular LCDs seem flat and dull. Sure there's the shiny coating, but in a desktop environment, where I could control the light, I don't imagine it's too much of a problem. My father has a Sony X-brite display right next to a 20" Apple Cinema Display, and honestly, they are both very good displays. The Sony's image just seems to "pop" more than the Cinema Display's.
On a laptop, I could see how it'd be a hassle, using it in different and uncontrollable lighting conditions.
