I concur ("conquer" if you are Carl from the Simpsons of course) with most everyone else so far.
But...yea, my 27" has alot of white space now, even with FF only taking up 60% of my screen normally. I miss the wider MR...even using a % value instead of pixel width would be nice.
Apples site is not exactly a forum where people write lots of text which will now run a little longer down than across.
Yeah, I'm not liking the "skinny" look either. On a larger monitor (24" here), there's almost as much white space to the sides as there is content in the center. It'd look better either expanded, or fill the useless space with something.
