It may be that the entire window/viewscreen discussion is null and void... Can it be that a window also doubles as a viewscreen?
Sometimes it seems to me that the nuEnterprise's bridge uses something like a HUD. In the photo I mentioned in an earlier post (the publicity shot with McCoy and the others standing in front of what seems to be a window), you not only have a view outside, but the speed of the starship ('warp factor such-and-such') superimposed onto it. Also, in another photo, the film.com exclusive with Nero on the big screen and Kirk and Spock standing in front of him (sorry I don't have the URL), it looks like you see not only Nero, but also some kind of nebula behind him, just as if his transmission was somehow projected onto the window.
