Why Not Vista?
I could not have said it better myself.
“This isn’t a matter of dissing Microsoft, but Intel information technology staff just found no compelling case for adopting Vista,” the person said. [Et Tu, Intel? Chip Giant Wont Embrace Microsofts Windows Vista]
I know there is a better security model/etc under the covers for Vista, but when it comes to end user features, there is nothing that makes me say "I want that".
