Story here from the Columbia Missourian.
I just got a new laptop from the university at which I work, loaded with Vista of course. I'd heard the horror stories, but decided to take my chances. Most of my programs worked fine on Vista, but one of the most important - SAS - would not let me install it. So I'm going back to XP.
The IT people say I'm "downgrading" to XP (their word, not mine). I think I'm upgrading.
