Anandtech review.
Conclusions:
1. The new Unibody MacBooks are far glossier than the plastic white MacBooks. It's OK indoors, but the unibody MB's matte screen a total mess outdoors.
The old MB's screen was far less glossy.
2. When comparing only the previous generation MBP's glossy and matte screens, the matte screen is clearly superior. Remember that these displays have the same brightness and LCD panel models, so the difference is
strictly due to the matte and glossy finishes.
3. The new unibody MBPs are much glossier than old glossy MBP, so imagine the unibody MBPs outdoors! It would be even worse! However, it's brighter, so the difference may not be as great.
Here's a photo of 2 glossy MBPs.

4. If you're in the shade, the glossy screen may be usable.
5. New unibody MB's screen viewing angles are better than previous white MB's screen.
6. When indoors, the reviewer PREFERS the glossy screen of the new unibody MBPs.
