I agree completely. It was a close choice for me between the cameras and the D100 is better in several respects.
I personally don't use flash much, and I can work manually just fine for studio style shooting for work. So the flash issue didn't weigh as heavily for me as it could for someone else. It was, however, a tipping point with the other pros and cons.
I really do hope Nikon gets past this DX flash thing with the next generation of cameras. If they do keep pushing it, I think it will be to sell more speedlights to DSLR owners rather than technical incompetence.
