>>Upgrade while it is free, unless you fancy going LINUX.
What on earth has that got to do with it.
This user is on Windows and is asking if they should upgrade to another version of Windows.
Most non-technical computers users have no idea what Linux is, where to get it from, how to install it, why they need it.
If this user is on Windows 8 and is fairly happy with it then they can stay on W8, why should they even consider going to linux.
It is like a person with a Ford Fiesta asking if they should upgrade to a Ford Focus and suggesting they buy a motorbike instead.
p.s., I have worked in IT for 30 years and also know what I am talking about. I can remember people pushing Linux 15 years ago, then 10 years ago, and they user base has hardly risen in that time.
MOST ORDINARY COMPUTER USERS DON'T WANT OR NEED LINUX.
