The amount of times I absolutely cringe from super lux UI which clearly a lot of time and energy went into prettifying at the absolute expense of usability and affordances. I love Apple TV but flip to any screen with multiple buttons and not being able to tell which button is selected. Or the Russian Roulette of Youtube trying to select any of the overlayed buttons on the actual video frame. I would 1000% trade shiny for more usablility in 99% of apps.
