Well, like most I said it depends. I have not yet been in a situation where I said tomyself, I sure wish this was full farme. With my 18mm lens eqiv. to 27mm on my K10D I can go as wide, if not wider than I ever really need to. The only real benefit I can see to FF DSLRs is the wider focal range, and the ability to cram in more pixels without the drawback of increased pixel density...ie, Canon EOS 1Ds MKIII 21MP. With current technology it would be impossible to get such a high pixel count from an APS sized sesor, at least and still get a decent image.

So unless you need wider angles, or just feel you have need to truly begin to approach the resolution of 35mm film, then FF cameras are really still out of the reach of most people, and in my case, not really all that desierable to begin with. It's like a bought a 1.5x teleconverter with no extra glass to screw up my light and dull my images.
