While many users love Windows XP and maintain that they haven't moved to Windows Vista or Windows 7 because they simply don't see the need, I can't help but believe money is still a major contributing factor in that decision. I translate it to "I like Windows XP, so it's not worth $200 for me to buy Windows 7." If Microsoft gave away Windows 7 for free, I think many of those holdouts would happily embrace the newer operating system.

Well, Microsoft isn't giving Windows 8 away for free, but it is making a Godfather-esque "offer you can't refuse". With Windows XP rapidly approaching its end of life in terms of Microsoft support, that $40 move to Windows 8 will be very appealing. But, the bargain offer has a time limit, so users only have until January 31, 2013 to decide.

Microsoft has a lot on the line. Beginning October 26 we'll see if Microsoft's gamble will pay off.
