No, you didn't. And I didn't say you did. What you did imply though was that (at least some of) the people still using XP do so because they think nothing has topped that OS. And I simply find it hard to imagine that there are such people out there, including the very ones still using XP. Of course, if I'm wrong and there are, then you're probably right and no update to Windows 8 would change their opinion about that.
never said it wasn't good enough. Not even close to that.
