Its taken me a long time, but I have finally upgraded to Vista. Its been remarkably painless apart from the mouse and the CONSTANT clicks of the continue button. But I am getting used to that and to be honest haven't noticed for a few days now. Sarah is going to freak though when she goes to Vista. She hates popup questions.
I have found a driver though for a latitude rather than an inspiron. I have my doubts on it working but I'll give it a go.
And it works!

I am just going to do a backup and then install Visual Studio 2008 beta 2, we'll see how that goes!
