I have a Macbook Air and the new 13" macbook pro. I see that the Macbook Air is much brighter than the 13" macbook pro (under the same ambient lighting, both set to maximum brightness). I was told the reason for this difference is because of the lack of the glass layer on the Air. Is that really true ? If so, can you please let me know if I'd be able to get the same brightness I get on the Air on the Pro also by just removing the glass layer on my 13" macbook pro. TechRestore offers such a service for $134, which is simply a subset of their service for matte replacement (I don't want the matte replacement as I like the glossy screen). But since such a service would void my warranty and return policy, I want to be really sure before getting it done with them. I'd greatly appreciate any inputs/advice.
