How can you tell for sure that Vista is a failure?

A small item I came across (Thanks to the Mixx Community!) states that Microsoft reports that the counterfeit rate of Vista is half that of XP. Microsoft is basing their statement on Windows Genuine Advantage validation failures, along with other internal data.

Microsoft, of course, attributes this success to the "robust security" of Vista. They are almost claiming that the war on piracy has been won.

I think there must be a different reason as to why Vista is not pirated as Windows XP - it's because Vista is such a terrible OS, that very few actually want to try it out - even as a pirated version. After a very annoying expericnce with Vista a while ago, I wouldn't install this horrible thing on a computer of mine, even if Bill Gates himself offers it to me for free.

There are more and more options out there to those who want a good operating system - a lot of them are free or close to it. If you insist on a Microsoft product, my advice to you is the rule of thumb I always give: Never install a new Microsoft product. Wait AT LEAST two years for most of the bugs to die. And even then - reconsider.
