Re: Windows 8 isn't a good comparison
"Win8 was damn close to free at launch - $39.99/£24.99 - for the Pro version. Still didn't sell, hence actually free this time."
Yep, I moved from Win 7 Home Premium to win 8 Pro for the figure you quote. I am now on 10 Pro. Not bad really. Still, not as good value as the other option on GRUB.
