I use my laptop mostly indoors in my home office with controlled lighting. The glossy screen looks better, deeper blacks, more vibrant colors, etc... While I wouldn't use it for photo or pre-press work, I really like it in general.
But isn't the point of a laptop portability? The glossy screen makes it significantly less portable -- in anything but ideal lighting, everything in front of the screen is reflected in a way that interferes with the intended image. That just doesn't sound conducive to usefulness in a laptop.
If you just use it inside your home office, why buy a laptop in the first place?
I said "mostly". I also use it in my dining room, my media room, out on my back deck, in my yard, at the local coffee shop, on planes (way too much), at client sites, in hotels, at friends houses, at my mom's house, in the car, and so on.
The only time glare has been a significant problem is when I'm outside (at my house or a coffee shop) and the sun is in the wrong position (solved this on my deck with a patio umbrella). For what it's worth, the same conditions where the glare is bad tend to make my previous matte 15" mbp totally unusable (washed out).
Again, I don't do photo work, but for e-mail, coding, etc... it takes a lot for the glare to get to the point where it interferes, and the matte screen is usually useless long before then.
It can be hard to use a desktop sitting on the couch in your home office. The laptop takes up a lot less room when your home office is also your entertainment room.
