I think it works when the 2nd half of the marketing campaign pushes the idea: "Vista SP1 has fixed most of those issues now". (disclaimer: I have no idea if that is true or not, but it should work as a marketing campaign)
It had other foibles as well and managed to crash due to driver conflicts and other issues. All in all, I much more satisfied being back on XP even though I'm missing out on some of Vista's new eye candy.
