I don't notice much of FW 4.0, except better AF performance with some lenses, especially the 60mm.
I stick with single point AF as I did before and I don't have to go into the menu more often than I used to. That is hardly ever, actually.
So, as others have pointed out before me, the new Firmware gives you more options. If you take advantage of them, of course the camera gets slightly more complicated. That's the price for the added versatility, you can't have one without the other.
But if you don't, the user experience is just like before. How can anyone complain about that ?
