Glossiness increases the contrast between lights and darks so that movies and other things look crisper. You find it mostly on media-centered systems. On a lot of laptops it is either the only option or available for about $25 more.
I don't think OSX and Vista have too much to do with it. My brother's Macbook doesn't have a glossy screen and I'm not sure they even offer it. I'm not sure about the other models though. Vista is only software, since MSFT doesn't make the hardware on PCs, so I don't see how that contributes to glossy screens.
The reason I would give for it is that it is a way to add a feature to a product that differentiates it from other products. It doesn't matter that the glossy screens have enough negative effects to counter the 1 advantage. Company A came out with it to sell more computers, so companies B, C, and D all had to develop their own version to compete. Consumers can be silly that way. I was.
I think Apple might have a different process for making their screens, because my brother's macbook doesn't look reflective at all. They probably just do a better job with their glossy screens.
