Asia is not stuck on XP because it's more or less secure. Asia is stuck on XP simply because of piracy (which kind of seems to argue it's less secure, but anyway).
Most people over there are running pirated XP. I worked at a company that had Asian partners and we found even legitimate companies over there had office consoles on Pirated XP. That was a shock to us.
The really shitty downside of this is most users are using IE8 or lower and sometimes newer versions of .NET couldn't be used in our software builds. Business dudes always wanted us to design our web pages to appease these customers, which became increasingly difficult as technology goes forth.
