I just go my XPS420 delivered from Dell yesterday. I would have ordered it with Windows XP installed if it had been an option, but since it wasn't I figured I would at least give Vista a try. I do a lot of work at home and my employer supplied software doesn't support Vista yet. I have already started running into problems and I don't really have the spare time right now to be a guinea pig for Vista (I need to get work done). I own a copy of XP Professional, so I thought I would do a clean install over the OEM supplied Vista OS. This seems like it should be a pretty straightforward process (reformat HD and do a clean install). Are there any pitfalls to this that I am not considering?

Thanks!
