I love the clean look. I was trying to think of some drawback, such as when I am doing training and trying to point out some button, I used to be able to say "the brown steering wheel" or whatever, but actually I think the whole toolbar is much more easily readable now, and it's easier on the eye to pick up out a shape e.g. the "target" or the "list of lines", or the "gear-shaped thingy", etc. to refer to the buttons.
