Starships have had windows for viewscreens (third pic down) since the sixties. I, for one, appreciate this slavish devotion to canon. 
Really, it's no sillier than the classic bridge placement or the skylight... the advantage, though, is that it makes the viewscreen more dynamic and better integrates the bridge set with the exterior CGI, helping to create the illusion that our heroes are actually on a starship.
NOTE: I did not read the entire thread, as I find such topics tedious. Feel free to disregard my comments if they're terribly repetitive.
EDIT TO ADD: Also, it should be noted that, in the new movie, the hull of the freakin' starship started to crack before the window did. Them things is made of stern stuff.
