Alright, thought I'd pop back in and offer my two cents.
I couldn't decide between the glossy or matte, so I decided to buy the glossy and give it a whirl, knowing I could return it within 14 days. I strongly believed that by using the glossy it would merely consolidate my decision to go with the matte.
Anyway, after about a week, I can say that I am not entirely dissatisfied with the glossy. I think some accounts of glare have been exaggerated. Now, in my case, it's largely a desktop replacement, so I don't really have to deal with changing lighting conditions.
I will return the laptop tomorrow, and upgrade to the higher processor and faster HD, and probably the matte screen. Not because I dislike the glossy, just that I can get the same quality out of the matte without needing to worry about lighting conditions. The sacrifice I will be making is only aesthetic (glossy looks nicer IMO), but this is a machine for school, so I'm afraid it's function over form for me.
Well, I've tried to be as unbiased as possible. As a portable machine, I can't really see why anybody would select the glossy over the matte (unless they were hung up on the looks).
I will pick matte, but that's not to say the glossy isn't tempting me. After all, I'm a designer. It's all about the look.
Anyway, hope this helps.
Also, so happy I've gone with the 17". The added real estate and resolution is incredible. And they size, very manageable. Almost the same weight as my last 15" laptop!
