OMG this is a beast of a thread.
At first look, I hated the look of Yosemite. My knee jerk reaction was that Apple took OS X off a cliff. The dock looked horrible and everything seemed washed out. My hope was that I could tolerate it until Apple fixed an obvious fatal flaw. Well, time goes by. Working with Yosemite betas for awhile on one computer and now release version on 3 computers (MBPr, MPA, older MBP), I really like the look and feel. In fact, I prefer it to Mavericks. I think I initially fell into the old trap where what I didn't like was that it was different, only to realize that when I let it be different, I actually liked it. Conclusion at this point: Yosemite look and feel is a positive change.
