I'm lucky to live in a big enough city that there is an Apple store in the city center, I went to check out the Macbooks last week and I have to say the glossy screens are not as bad as I thought, they have pretty bright lighting in the store and it didn't seem to cause any problems. The colours definatly look a lot more vibrant than a normal screen, I think you'd get used to it after a while.
I can definatly say that the screens on the Macbooks are nowhere near as bad as some of the laptops I saw in a popular electronics store opposite the Apple store. Out of about 20 display laptops, only 1 had a normal matte screen, some of the glossy screens were so bad that you couldn't get the screen into a position where it was completely visible without reflections.
