The advances made are very interesting, sadly, the choice of aesthetics minimizes their actual usefulness. Simply put, the decision to use a color-scheme of pastels-on-pastels, though classy and distinctive, makes the data presented almost illegible. Granted, my vision is not as powerful as it was, but then, I know there are many who are in the same boat.
If you were to keep the elegant graphical aesthetics, but simply increase the contrast (foreground to background). If you were to include a utility that would allow the user to make this adjustment to suit his/her needs, you would fully redeem your Apps utility, without sacrificing your aesthetic elegance,
