Bitt, when you looked it up, did you see any other differences between the models, or was the screen type an independant selection?

I just found the first 15" (15.4", really) widescreen laptop in the small business section, so I don't know that that's the exact model your dad has. But, on that one, the screen selection was a top-level option. That is, you had to choose that, CPU and something else (maybe office suite?) before doing the real customization. I doubt that there were further differences, but I don't know. Just go over to dell.com and see. It should be easy to find.

If your Dad does have a Dell rep, then maybe you ought to blame him.
