Well went to the Apple Store Chadstone today to check out the various laptops there and decide if I wanted to go 13" (Portability), or 15" (Productivity).
Having previously owned a 15" MBP I started first with the 13". To me, this looked extremely portable, good solid design (Although for some reason I was more biased to the polycarbonate design than the alu), good feel to it and plenty of screen real estate for a small screen.
Unfortunately, it was at that point the glare coming off the glossy screen really began to irritate me. I couldnt focus on the screen, to me all those extra 'popping' colours were lost in the reflections bouncing off the display. Now, I don't know if it was all the comments coming off the forums...Or simply the fact that when I moved slightly to the left and gazed eyes on the 15" Anti Glare display that I was completely sold...
5 more subsequent minutes of staring at the matte screen in utter amazement, I handed over the credit card for the bigger brother. To me, the extra bulk of the 15" was a minor tradeoff for such a stunning screen, with better screen real estate and blazingly fast processor.
As others have said, do yourselves a favour and get down to the store to see one. Even if you are comfortable with a gloss screen. I've seen many iMacs in the home and these are often in lounge rooms or bedrooms, often used in mornings and late evenings and often in dimly lit environments. With the MacBook Pro Anti-Glare displays; outdoors, caffé's or brightly lit offices or workplaces will be a pleasure to work in.
Sorry for my rant, but just my .02c on why I made the switch from Glossy to Matte.
