I don't find it difficult to hold, though I don't like the "feel" of it as much as my old favorite, the D300, which I prefer over my D700 in that regard.
I find that weight and shape don't matter to me much once I start shooting since I'm so involved with my subjects. You're really going to enjoy the D800 once you've shot it for a while. I didn't like mine at first, but now I'm sold on it.
