Can you substantiate those claims or are you just
making stuff up off the top of your head?
I honestly don't see the point of these types of "defenses" of Yosemite. What are you hoping to accomplish? Do you seriously think you can convince someone who thinks it's UGLY that it's NOT ugly by saying other people have thought so about previous versions in the past??? There's ZERO logic there. I'm sure those people wouldn't have been appeased by such illogical arguments either. It's GREAT that you just LOVE Yosemite (and possibly every single thing Apple does based on most fans emotional defensive reactions on here that never seem to end). Go enjoy it. Spend all day worshiping it if that's what appeals to you. But don't think you'll suddenly make the world appear all rose-tinted to those that can plainly see for themselves that Johnny Ive has ZERO talent when it comes to making and/or directing ART.
Frankly, I've seen better interface artwork in the 1980s, which quite honestly is what Yosemite's GUI reminds me of, a 1980's flat, boring interface. Back then it was due to limited colors and CPU power being available. I'm going to guess that Yosemite won't save me any CPU cycles, though. Apple has had a way of bloating most OS X releases since Tiger (and yes Snow Leopard measured slower here than Leopard on my Macbook Pro also; some improvement that "optimization release" was. The only thing it saved was disk space by wiping out PPC code and support (Thanks to Apple for artificially shortening the life of the last PPC Mac Pros. A lot of people appreciated that as well). I'm not a big fan of most things Apple does. It is only the fact that Windows has been historically a messy register-based disaster of crashes and malware that I've stuck with Apple. It's certainly not been for the outstanding gaming support Apple has provided gaming developers and the top notch GPUs and drivers they've provided us with, that's for certain.
