SimoAmi's example is how OS4 should look to make
attention from serious world.
I disagree (no surprise I guess :-) )
Don't get me wrong, I love SimoAmi's stuff. I disliked the way that buttons look when pressed (there is not enough optical clue IMO), but things like that could be tuned. However, it was important that it still was looking somewhat like Intuition - and I think that is what the new look does.
If people fancy a more fancy theme, they can use that, but first and foremost a GUI should be functional.
