Take it from somebody who just bought an Acura in December,...a Honda is not an Acura. At least a US Honda isn't. The leather and interior materials are nicer in an Acura. The stereo is MUCH better in an Acura. The handling and steering is superior in an Acura. Some options on my Acura aren't even offered on a Honda.
That said, with regard to cameras, FX is better than DX in most circumstances, but not all. A lot of us would like an upgraded D7000. DX is better for telephoto photography, especially field sports, birding, and other wildlife - and especially if you cannot afford lenses that cost as much as a used Honda. On my camera budget, I would have to make severe compromises to my sports photography if I had to give up DX. In the ideal world, I'd have a D600 and an upgraded DX camera.
