What operation system are you using?

Hey folks.

Which OP systems do you use on your PC's? I personally have Windows 7 Ultimate x64 on my old laptop and Windows 8.1 Pro x64 on the current up-to-date PC. I personally like the 7 better but 8 looks smoother and maybe that's my preferred OP system right now since I'm used to use it for some time now.

My Android tablet runs on 4.2.2, so does my 4 Android phones(2 are actually my wives and 2 are mine).
