I now need to get used to it like I did with Mac OS X.

Indeed!
I just switched back from Mac to Linux. After 3 years I needed an upgrade and on that occasion I decided to go for more freedom, because as heavy user and developer I often hit the “like it or leave” barrier of Apple.
Because of that look for freedom I instantly switched to KDE desktop after installing Ubuntu.
I absolutely understand that unification and simplification is useful when targeting a large user base. (Freedom always comes at a cost, in case somebody didn’t know.)
As long as Ubuntu makes it that easy to switch to something else, I won’t complain about this Apple-ish attitude in regard to Unity…
