"What if the reason why most PCs are still running XP has nothing to do with whether Vista is “good” or “bad”, but rather is the result of indifference on the part of whoever owns these untold millions of XP machines, be they at home or in a corporate IT environment. I.e., that switching to Vista, regardless of Vista’s merits, seemed like too much work and too much new stuff to learn;"

No, no and no. Vista is just horrible, usability wise. I bought a laptop for my parents, and I curse I didn't wipe it out, and install xp instead. I get twice more "how do i do this' request, than I got with XP.

Finally, last month my dad asked me if I could install the older OS he had on the other computer, as he liked XP much better.

Horrible product.

I have used it personally at work, and at my home computer I sticked with XP.
