I bought a refurb laptop this week because my 10 year old machine seemed to be dying.It came with Windows 10 and I spent an hour or so learning how intrusive and how slow it was.It amazed me just how hard it was to prevent Microsoft and everybody else from hoovering up my data.So within three hours I had a dual boot machine running Linux.I don't think there is anything to make me run Windows again,but I could if I had to.It would take a lot to get me back there though.
