Thanks again for your help, AppleMacster. For someone whose first home PC ran in DOS, I'm beginning to wonder what I've actually learnt in the last ten years!
My main use for the new laptop is to edit a load of digital camcorder stuff plus the occasional bit of work. I presume that I would need iDVD to put the edited videos onto disc, so it looks like I need to go for the 2.0GHz model.
Right, deep breath time
