Yeah, too bad about the "glass plated" imac. Why don't they just offer a choice of plates that the user can install and change at will? That way we could have glossy or matte depending one what we're doing with the machine. How much could this cost? Not too much I would imagine, and it's novel. It would be a great selling point for Apple innovativeness!
Optical quality glass is neither cheap nor light. If you have seen the "tear-downs" of the iMac on the web, you need to use a special tool to safely remove and install it.
I expect the warranty claims would be high (as a percentage of total systems) both from actual defects and people damaging/breaking the glass removing and installing it.
Yeah... that would be nice, but as CWallace mentions in the post above, I am sure it would be a horrible and intensive process to do that, and then you'd still have a glossy piece of glass over top of the matte display, which would make it glossy still. There used to be screen protectors for the old iBook G4s that once applied, would turn the matte display glossy, and if you applied it wrong, it was a horrible thing to look at.
I'd rather Apple had made the machine look good, and still be somewhat functional. They are keeping up with their track record of designing great products, but sacrificing a bit too much for that design.
Even now I love the MBP design, but would love to have one that was a bit fresher, but didn't take away from the functionality that is already there, and maybe even added some to it. I love that the new iMac has FW800, and a fresh design, but can understand the desire for glossy.
Personally and professionally, it's still kind of overrated.
p.s. and if you really need it for color specific jobs and just don't want to be bothered with a glossy screen, then the Mac Pro is really the best option. I struggled to get enough cash for my first pro machine, but I knew that I didn't want to bother with the iMac, I went straight for the Power Mac.
