About Vista "flop": XP was the same, if not worse, in the first years.
www.tweakguides.com/VA_2...."Interestingly, when Windows XP Service Pack 1 (SP1) was released a year later, it received even lower scores from CNET at 6/10, and 4.6/10 from users. Even by 2004, three years after XP was released, some people were still voicing how much they hated Windows XP and wanted to revert back to Windows 98/ME."
You're right that in the beginning, nobody liked XP. But this changed rapidly, and I don't think this is the same with Vista.
