I agree with this. In addition, these designs all center themselves around app-specific themes, which is unfortunate because (at least IMO) one of the biggest benefits of a native desktop app is that it conforms to the system's look and feel by using standard widgets. Throwing that out the window in favor of style seems wasteful. The desktop apps that impress me most are those with designs that create beauty through the stock system look and feel.
