Their real mistake was messing with hardware certification — typical Microsoft mind game of the time, but that time it backfired. AFAIR there were two grades: computers that were supposed to run Vista well, and those that barely met the minimum requirements — normal people got confused and couldn't distinguish the two, they bought laptops with a shiny sticker at a price that seemed very attractive only to find out how awfully it runs. And of course they were blaming Vista for it.
