I'm at the crossroads, anybody else?

If you only view on screen, a D800 is overkill. Your main benefit would be the greater dynamic range. That may not be enough to justify the extra weight and bulk.

Personally, I like big prints. I generally print one of three sizes: 16x24" (small), 20x30" (standard), and 24x36" (large). The D800 is very much worthwhile to me.

With film, my travel camera was a Pentax 645 with several lenses. I also shot with a 4x5. My Nikon SLR was mainly used when slides were needed for a specific purpose, and didn't get much use.

As technology advances, I can see where someone would prefer the increased freedom of using a smaller lighter camera. I prefer to go with improved quality.

Henri Cartier-Bresson didn't need an 8x10 camera to make great photos.
