No, but I'm more likely to try it than ever install Vista. One of my brothers bought a new PC which was infected with Vista and I've seen Pentium 2 machines run quicker and more smoothly. I remember when it was released, one of the IT techies at the college I work at described Vista as the new Windows ME and nothing I have seen, heard or read about it makes me think he was being unfair.
Twelve months on, it appears that Vista is only for those whose new PCs are infected with it, or those who cannot resist playing keep up with the Joneses.
