I love vista.
No, I don't use it, and I wouldn't want to. However, its hardware requirements are so ridiculously high, that hardware manufacturers these days have no option but to seriously bump the performance of their systems. As a result, they ship with ridiculous amounts of RAM and CPU power, while still keeping prices reasonable.
Of course performance still sucks your pants off if you indeed do use Vista, but not if you use an actual operating system.
I love vista.
i just bought an hp latop dv3 2150ep[0] with 4GB ram !!! It was a cheap buy, since it is 13.3'' and is has a recent dual core processor processor.
In vista, it has an ok performance ... but in linuxm stock debian gnome install boots and shuts down in +/- 7 seconds :P
Everything is VERY VERY fast. eheheh
