Good god, I can't believe it used to look like that ��
I know how you feel, sometimes a friend would show me something on his iPhone - and something would look different and beautiful, and almost "comfortable" somehow, but for a second I couldn't figure what it is. Then I notice it's pre iOS7.
That looks absolutely fine.
I have to wonder how many people who adore Yosemite's flat/boring look would jump back onto the 3D bandwagon if Apple decided yet again that 3D was the way forward. While I have no doubt that some people genuinely love Yosemite's look over every other previous version, I can't help but feel many people love it simply because Apple deems it the future and Apple is infallible.
I think those people who genuinely love Yosemite's look are people who are new to Apple or who've only been there for a few years. Then, when you say something like that, there's always one Apple die hard fan who comes and says he's been using Apple since the 80s and how he loves Yosemite so much. In this case we'd go back to your first example, basically the "Apple slaves", people who usually have a weak personality and therefore follow and do everything you tell them.

As for the first sort of people - I think these people just switched to Apple because Macbook and that sort of stuff are in now, not because they like the system itself. Deep inside they prefer the Windows for what it is, and Apple for the brand and the logo. I know some people who installed Windows on their MacBook for example, and don't use OSX at all, or just barely.
And since these new users are a big share of Apple's customers now, it's logical that Apple will adapt to them, by giving them what they *really* want - deep inside. Which is not the Apple look, but the Windows/Android/Whatever look, with the Apple logo stamped on it.
But it will be a hard day for Apple when these customers, who are not loyal customers, will be gone… if you look at the past, Apple was nearly unknown and it was almost "out" and "not cool" here in Europe not even that long ago. People laughed at you when you told them you had a Mac. I was one of the only ones who had Apple computers. With the iPod, Apple quickly became "in". But it's not a secret that fame that comes in so quickly, over such a short period of time, can disappear just as fast. :roll eyes: So Apple should think about which customers are the more important ones, the long-term customers or the short-trend-customers.
