Best of luck with the change. I built a Linux system (lower end system so only used Elementary) last year but have not switched over yet. Just testing the waters. Got to push myself to make the switch. Certainly frustrated with Windows and have no desire to get caught up in the Mac propriatary world.
So far I am happy and still have my 2nd screen working. That is what pushed me over the edge was the updates kept making my 2nd monitor not work which is just unacceptable. So much more efficient having 2 screens.
