Does it matter which way you hold the camera while shooting vertically? I've always held mine shutter side down (without a grip that is), but this seems contrary to the way others hold it. Does it make a difference? I feel I can balance the camera better if it's not dangling down from my hand, but being supported by my hand.
That's how I hold mine, even the 1D3 which has a grip. It lets me keep both elbows tucked in and steady instead of leaving one wing flapping madly away. The left hand still bears most of the weight, as it always should.

Another point about the right-side-down being the traditional Portait orientation mode...
Imagine trying to use a film camera, with the rapid film advance lever which ordinarily takes a flip of the wrist toward the right, and trying to cock the shutter and wind the film with the lever now twisting DOWNward!!!
That's about the only reason for flipping the right side up that makes any sense. However, it's irrelevant with digital cameras or film cameras with built-in winders. And with small P&S cameras, tipping the right end down gets the flash above the lens for better results.
