I am unpleasantly surprised by the new 3D dock floor. It just looks awkward when your screen is not on a 30 degree angle, especially when your screen is up straight. > http://www.apple.com/macosx/
My suggestion to Apple: why not dropping this fixed angle of the dock?! Every time you change the angle of your screen, the dock floor adapts itself to a pleasing angle in order to create this otherwise great 3D illusion.
