If you look around then you'll find plenty of threads on this. But I like matte a lot more because I wouldn't pay 2.5K for a 15 inch mirror.
 
There are a lot of threads of this already. With that being said, I was in the same predicament and decided that the matte screen was the right choice. Like iBookG4User said, I don't want a mirror that reflects everything. I want an easy-to-read "true color" screen. This is one of the main reasons I didn't even consider the MacBook when I was in the market.
 
lol, we really don't need another matte vs. glossy flamathon, but if you must know...

matte.
 
in an intresting twist to this thread, your more likely to get a yellow samsung screen if you get a 2.2 glossy.
 
After using both (at home), matte all the way. The glossy had too many distracting reflections. I'm very happy with the matte screen.
