I've had a ton of experience with Vista and I have plenty of negative things to say about it. If it does what you want it to do that's great, but it doesn't do what I want it to and I've also had a lot of performance issues. It has admittedly gotten better, I've been using it since the final retail version came out and I stick by my opinion that what was originally released was pretty awful. What they have now is passable for most people, and I still use it for one of my boxes because I need experience with it in order to be able to support other users. Don't get me wrong there are some good features in Vista, they just aren't features I'm particularly interested in myself... I have high hopes that Windows 7 will be enough of an improvement for me to recommend it for more than just specialized cases (Gamers who want DX10, or Media Center users who want to take advantage of some of the advances there). I'm an MSDN subscriber so I have Windows 7 beta now, I just haven't had a chance to install it yet. I'll let you know my opinion when I do.
