I hate it. I never should have settled for the glossy screen over the matte. What was I thinking ? Well, what I was thinking was that I wanted a more portable MacBook Pro than the 15" I already have and that I'd give the 15" to my wife and keep the 13".
Bad mistake, either way. For general use, I guess if you can find a spot where the reflection isn't so bad, then it's fine. But for professional work I'd say absolutely no because it's a huge distraction.
Yes, the colors are more vibrant, but that's to be expected and is the point of the screen. I still prefer the matte screen in terms of color rendition though because it gives me a slightly more accurate representation of how I want my prints to look, amongst a few other things.
Gloss to me is just annoying. As handsome as I am, I'd rather not look at myself all the time. ;D
But there's another point you should consider. If you're buying a MBP for professional graphic or photographic work, then you're likely to hook it up to an external monitor. Here's the thing though... If your logic is that the reflections/gloss shouldn't be too big a deal for those times when you're going totally mobile, you'd be wrong. The whole point of being mobile is to take your work with you... right ?
But if you want to sit at a coffee shop etc and work on a project, it might be hard to find the perfect spot to sit in unless you just don't care about the factors involved.
You should try and find a friend who has a glossy screen and ask to hang out and go mobile with it. The Apple stores usually keep them in such a position where they're not in direct line of sight of the sun, so take that for what it's worth.
Oh, and I even put a Moshi anti glare screen protector on mine. At first I thought it was great, but after having it on for so long and primarily using an external monitor, when I took it off to clean under the thing, I noticed that I was losing a LOT of light and resolution. So I wouldn't advise getting any of those screen things either. It works to block the light and reflections, but makes things pretty dull.
I'll personally never buy another glossy screen MBP again. And I can't wait for the next MBP model and sell my 13". (that's a head's up for people here).
