Aside from looking at the glossy/anti-glare threads and postings....
I can see the advantages of both. If you are mainly using it outdoors a lot... anti-glare would be the way to go. If not.... glossy is definitely a candidate for consideration.
Glossy Pros
- Text is more easy to read due to more vibrant colors, having read both text on the anti-glare and the glossy... I definitely felt i could read much faster on the glossy.
- Photos and colors pop more.. example is to open up iphoto and look at the dropshadows on the icons... glossy looks better and packs more punch.
- The black glass makes it look very high quality and expensive
However, on the anti-glare, photos could potentially be better because you can definitely see the entire photo without any reflections on the glass (this is apple store experience, which all the fluorescents are turned up)
Note that despite being anti-glare, lighting can still effect the display as the light is simply diffused on different parts of the screen. So if you wave your hand around it, you can see light blurry shadows that are very subtle, but you can tell light is definitely getting spread out in a way.
Being a fan of HD movies, the glossy display clearly looks better when watching any movie.
So.... really its just a matter if your OK with the reflections due to light, note that if the color is not black on the screen, you wont see your own reflection, only light from a window if your indoors.
Note that another option would be to keep the glossy display and get an external antiglare monitor to hook it up to.
Having looked at them both and working with both... the reflections in the apple store didnt bother me at all, but in terms of photos I did like how I could see the entire photograph on the anti-glare versus having to deal with some reflections in the glossy. However, the photos on the glossy did have an interesting "pop" effect that felt like they were much more lively.
Colors on both I think are very close, I dont do any image printing... though I do do a lot of photoshopping and I dont think it would really have any major negative effects during photo manipulation as badly as others may say.
So basically tradeoff of better looking glossy is reflections, or anti-glare not as good looking (both view and bezelwise), but can see entire screen.
So in the end the choice is yours... please let us know what you pick!
