Putting all that aside, you might even appreciate the true nature of an operating system: that by design it should fade out and not take your attention good or bad. It should present you with an experience that lets you focus on the tasks at hand or the content you take in, without pulling attention away from that for itself. Yosemite, once the newness becomes the norm, does just that. And that my friend, is objectively good design.
I've ran it since beta 1 which is a damn site longer than a week or two, and its as jarring and distracting now as it ever was.
A back-filled dock who's color changes depending upon the desktop background image resulting; in it varying from muted brown to in-your-face high vis pink,
a spotlight search that opens in the middle of the screen, no where near the menu bar control that launches it and is more fiddly to use than the one it replaced.
A grid view background of eyeball searing white unless I opt to take the hobsons choice of dark mode (and then invert the colors of the menu items from the traditional norm and turn those into a distraction instead).
A maximise window control that no longer behaves like it always did. With no way of overriding it without reaching for the keyboard every time. Still catches me out to this day.
Translucency that makes menu items harder to read A) depending on background image or b) whats in the window its opened over
Screaming blue folder icons that actually draw attention away from the folder names
Desaturated finder menu icons that strip the last useful color cues out of that part of the OS
Half assed folder opening animations that plain don't work as intended and instead just distract me with an annoying glitch
Likewise the degraded icon redraw in grid view (one of the few areas in prior versions of OSX that already had transparency and actually coped with it well until now)
Does it look lovely in static screen shots, with just the right choice of precanned backround image and carefully arranged windows? Absolutely.
Does it cope well as an actual live user experience, without blink-inducing, jarring effects and a load of attention-sapping "squinting n staring" required? Not on your life.
Its a tiresome distraction that most certainly
doesn't fade quietly into the background to allow me to focus in the way you suggest.
Its not even consistent. De-saturate this, transparency that on the one hand while ramping up the intensity of other screen elements (folder icons, drop down list selectors etc) for no appreciable reason or the other.
Its about as tasteful as an early 70s combo of screaming purple skin-tight bell bottomed loon pants and a bright orange bry-nylon shirt (with collar that reaches your nipples).
As a UI that minimizes distractions to get on with work its about as practical as wearing that gear to work too. Its only saving grace is it smacks of a fad whose time will be up just as quickly as those clothing choices were
