Running Yosemite on my retina MacBook Pro with no issues. I don't really know how I feel about the new iTunes but I don't have an issue with the design of the OS as far as the visual appearance goes. I'm still only a click away from using tools like 'dig' so it's far from iOS with windowing or a toy or whatever.
If anything the introduction of the iOS and Mac OS X integration through things like Handoff shows Apple are more than interested in keeping both around.
