I second your enthusiasm for Gnome. It really is in a great place right now and is my shell of choice on Linux. But I disagree with the Yosemite criticism. Unlike Linux, OS X actually has a large degree of uniformity between third-party apps thanks to Cocoa and (historically) the human interface guidelines. Apple just can't make sweeping changes to the OS X design without severely damaging the coherence of the OS X ecosystem; design changes have to be incremental. And they're doing a pretty good job. Yosemite brings design changes specifically optimised for high-DPI (font, line weights) and a general toning down of brashness (e.g. the new dock). I imagine the new 'dark mode' (which, let's face it, will be unseen by most consumers) is just a signal of things to come; I wouldn't be surprised to see a dark set of Cocoa controls in a future release too. But it'll take time. Honestly, I'm glad that Apple isn't being brash on the Mac. They can get away with it on iOS (the 6->7 transition) because it's such an active platform, with so much demand, that developers have put in the time and money to re-design, but a similar design transition on OS X would take much much longer and I imagine would be a lot more painful for the end user.
