The laptop I use came with Vista pre-installed and I don't see any reason to switch back to XP, so that's a roundabout "yes" answer, I guess.

Although at the same time, I still use an XP machine on occasion and don't see any great need or point in updating that.

Windows in general is still my least favourite of the operating systems I use regularly (the others being OS-X on the desktop and Kubuntu duel-booted on the laptop). I don't think Vista in particular has done much to sway that opinion in either direction.
