If they were anything like me I say nothing in the Vista features that I needed or didn't already have in XP Pro.
David,
There will always be people that look toward the future and are eager to try something new.
There will always be people that are comfortable with the old things and aren't eager for change. 
It has nothing to do with not trying something new but something practical, like what does it have that my existing OS hasn't got, do I need it enough to warrant the price and for me that answer was no.
In fact when I bought my new system just over a year ago I bought a new XP Pro OS, which actually costs more than a basic Vista Home version which would have been a downgrade from already using XP Pro.
Do you buy a new washing machine because its new and throw out a perfectly functional older one, I don't.
Do you buy a new TV just because it is new and Throw out the old functional one, I don't. It just so happens I have bought a new Samsung LED TV not just because it was new but because my existing set (old 29" CRT TV) was near the end of its effective life. So when I considered a replacement I looked at redundancy, by getting what is a relatively new technology (LED TV) I will be likely to keep it for much longer until the end if its life.
For me it is about practicalities, its what makes me an individual too
