Its September 2015, still all white background... 3 years and some 6 months with no improvement.
Apparently the big-corporate arrogance goes a long way. That does not surprise me, I am also in a big corporation, and I know this kind of bloated conduct on a daily base.
What surprises me, is the fact that making of a color scheme is a comparatively easy task, algorithmically and in terms of maintenance. So why not? Its not only Apple, look at the Android tug-of-war between black-background versions, followed by a hurricane of web posting asking for a white one, and later once they went all white as well, we see a hurricane of postings asking for a dark one, looking for a replacements of tools and apps.
Stunning for me the seemingly lack of consideration to cognitive properties of our eyes, politics and the lack of choice.
Screens, even the modern ones, are ACTIVE displays, they emit light. As opposed to the a PASSIVE display, such as our paper. A passive display reflects light, a percentage of the ambient light, always following its intensity. An active display is a glorified flashlight, shining into our eyes. You like it? Fine, but my eyes are also burning from it. And I am tired of the eternal fight for apps and solutions allowing me to display dark background and white letters.
