Basically the Mini and PowerBook G4 were a 3 chip solution (CPU-Integrated Intrepid Chipset-GPU), the Intel version is a 3 chip solution (CPU-North-South) -- adding the GPU is the 4th chip.
Just as a point of interest, this photograph of a MacBook motherboard shows 4 chips already.

EDIT: My mistake, this is actually a MacBook Pro motherboard.
While it's possible that a technical limitation is to blame, I'd argue that the decision to go with integrated graphics in the new Mac mini and MacBook probably has more to do with cost savings (as you hit upon with your $50 comment) and/or deliberate market segmentation. This is classic Apple behaviour. Cost saving and market segmentation aren't dirty words, but we seem as a community somewhat reluctant to admit that these factors drive almost as many design decisions as technical factors do. Every company does it, to differing degrees.
