Over the years I moved from windows to linux and now to osx. Why you might ask?
Well, this is simple: I no longer have the time to configure the system to work the way I want it to. It is just supposed to do as much as possible without my intervention.
Ubuntu came pretty close to that but sadly my old vaio was breaking down.
I’m using OSX now for a month and I’m more that just happy! There are things missing like the “select and paste with middle mouse button” that I’m used from ubuntu and the option to move windows with the mouse and the keyboard, but it is close enough.
