I use Vista on my Motion Computing LE1700 tabletPC and don't have any issues with it. I'll admit that I do most of my work on my main XP system, but it's not like Vista blows up or crashes frequently, if at all. You should check out Microsoft's Mojave Experiment where they show people a new version of Windows and then spring it on them that it's really Vista. If nothing else, the page has a crazy cool interactive UI.
