Get over yourself Gazoobee! If you are so offended that a California-based tech company has made an American or Californian reference in their product name then you should put your money where your mouth is and buy your technology from a company that is based in another country.
Interesting... There probably are a lot of people who think they are paying homage to a Top Gun character. If so, they will be quite surprised to learn what Apple is actually referring to! Mavericks really is a beautiful (and appropriate) metaphor! I wouldn't be surprised if Yosemite makes the cut for a future release. Apple will have a lot of fun with this naming convention and there are so many incredible places in California that they can name their software after.
Minimal, clean and transparent come to mind before "flat". And because of this new design, the overall look and feel becomes more dimensional, vibrant and exciting! I don't see the "Pastel Colors" that some here are referring to, maybe they are confused by the colors in the wallpaper or the icons that permeate through the opaque background.
