All in all a very pleasant upgrade. After reading about all the new features and iOS-like feel, I was surprised at how the changes seem really gradual. pros: still the most elegant OS, the performance seems a bit snappier (just my feeling). cons: The grayness of all the UI elements (e.g. Finder windows) together with the more square appearance of the buttons creates a more somber, less playful atmosphere.
