My point is that I rarely find my self shooting portrait orientation. Now, maybe this is something I'll learn to appreciate and do eventually, but not for now.
Sorry, I think there may be some confusion. We're talking about portrait orientation - not portraits.
The problem is that the 645 must be tilted on its side to get portrait orientation, the RB has a rotating back that allows the camera to stay upright. That makes the RB much easier to use than the 645 in portrait orientation.
