A glass window on the bridge.
Transparent aluminum, of course.
Really, though, having an actual window on the front of the bridge seems rather handy if the viewscreen goes out. If anything, it's an improvement.
I can't really defend the engineering 'set,' though. It served its purpose in the movie, but the (prohibitively expensive, apparently) concept art for what was originally proposed for engineering was much better.
The blogger in the OP is really off the hinge, though. Abrams' movie had some legitimate flaws, but claiming that it did everything it could to change the characters from the ones the geeks knew and loved is a stretch. I'm about as big a geek as they come, and I had serious reservations before seeing the movie, but I could certainly recognize the characters that I've loved for two decades.
