Mac OSX is the least customized OS I have ever done myself. I have very few customizations because the default settings and UI are fine. Coming from Ubuntu and Windows, I think Mac's UX is quite nice. The two exceptions are rename (I want to old Windows double-tap style) and the Preview program. I want to be able to view images forth and back with my arrow keys by default. The finder is also a little annoying sometimes but I didn't get a separate program but maybe I will. One absolute must-correct issue in the future is Mac, Windows and all Linux distro should share same set of commands. Most Unix commands are available cross-platform but a few aren't. Unfortunately, that's not possible :( And forget about the difference between Windows commands and Linux commands. I could live with the difference, but, oh, it's 2014 and I hope one day we don't have to have live with difference. Lastly, I got a maxed-out MacBook Pro 15" (16G RAM, 1T SSD) thus dumping an estimated $1,000 profit into Apple’s cash hoard. You sure? A 15" retina max 1TB and 16GB is $3000, not $1000. I think you meant an extra $1000 profit.
