Windows 8 will have a much better price if you buy it from Amazon. Also no, it is not proportional to it's quality, It's a fantastic operating system despite what people think about the "metro" interface.
I got my upgrade key for $15 last year. People can still pickup the Windows 8 Pro upgrade key for $70. Nevertheless, I said inversely proportional, at this point Windows has nothing grand going for it as Ubuntu and OS X are just as stable. The fact that windows is still a monopoly and maintains 90%+ of the OS market share enables it to maintain a price premium simply because more developers develop programs for this platform and Apple still not providing universal hardware support. With China and select governments making a push for a transition from XP to Linus over the next few years, Linus may finally start eating away at Microsofts market share and finally force the monopoly to start pricing their products competitively
