Channel 10 has a video up today to start off Windows Vista Week (even a pretty new banner just for the occassion ;)) about installing Windows Vista. I've installed Windows Vista 18 hundred million billion times since I've been running it for a long, long time, but I think this video is interesting in showing that it's easy to install (sorry for linking directly to the mov file, but Apple's site doesn't have permalinks for their videos).
