Well, one person did put a matte screen in their MacBook:I have tried one of those at the Apple store in NJ today.
Two issues:
1. the Apple key is 4 keys away from the left, instead of 3, as on my desktop keyboard . What is the "fn" function key for? Very confusing.
2. The screen is horrible!!! I just cannot stand these glossy screens. For me that is the one show-stopper. I need a matte screen.
Otherwise the laptop was very snappy. Performance was great except that it easily choked on 1080p quicktime videos. The weight is very light, the thin body makes you forget that it is longer than the 12" Powerbook by a good inch (depth is about the same).
We are still waiting for a better small, light Powerbook to replace our 12" Powerbook. Unfortunately, because of the glossy screen, it is our conclusion that the Powerbook 12" remains the best travel laptop. We still use it professionally for that purpose. If it was just as fast or as thin as the Powerbook Air, though....
Not having a CD drive, Firewire, or a removable battery do not matter to us at all.

Don't know about MacBook Air though and how that process will go.
