I'm going to be installing Linux over my wife's W8.1 system on her laptop. Not because I am a Linux geek but because she is totally fed up with it not behaving itself. She is sick of stuff requiring a reboot when she wants to use it, yes she can defer it (mostly but not always) but that's not the point it should not be required. On her old laptop which had Linux she was more than happy with it but this new (relatively) one had to wait for Linux to catch up with Nvidia Optimus (an Nvidia issue not a Linux one), and now it has I will be finally removing Windows from it. One of the final straws was this update thing, Windows has a totally useless update process - the design of Windows requiring updates and reboots so often is so 19th century it is not true. I can set up a Linux system for her which looks exactly like her W8.1 system that she does not notice and the likelyhood of it requiring a reboot is so small, even when it does she does not notice as it does not complain and just gets on with it on shutdown and the next boot.
I will continue with W7 for my weather station, not because I like it but because the author has not provided a suitable Linux version of the software. The Linux software which does exist is not yet good enough, but as soon as it is be assured I willl dump Windows for good.
Sorry rant off - but Windows is so 19th century its not true.
