I APPLAUD Apple for demonstrating the commitment to the environment. Aluminum and glass are recyclable materials, and their systems have been arsenic, mercury and PVC free for a long time now. Everyone complains about the "glossy" glass displays, but research the difference between glass and plastic fronts, not just on the environment but also on color/gamma correction.
There's nothing ecological in adding
extra glass in front of display. More bulk and wasted energy. It would be much more ecological just to leave that glass not being manufactured.
1/3 of carbon footprint of IT gadgets comes from manufacturing them, so the most ecological way would be using state-of-the-art technology, so the product wouldn't get obsolete so fast and therefore would have longer life span.
Since there's already support for 10-bit colors in Windows7 and we have this monitor from HP:

, I'd say, IMHO, it's no brainer to me which I will choose.
I'm not sure if OsX will ever get 10-bit colors, but my next display, computer & os will have it.
Btw, how much would it cost for me to get GPU with miniDP to my MP1,1 (2006)? Or does it even exist?
And about PQ difference between glass and plastic fronts.
There's 100 types of both, so it really depends on combination. There's no rule of thumb.
