What about actual features?
Years ago a university design team was working on a project and I was disappointed in the lack of color in the interface. The response was "color has meaning". Don't color things just to look pretty, it needs to represent meaning.

sounds terrible
9to5 says there are a host of new features but didn't detail them.
