For me, anything smaller than 5x7 is "toy format". That said, I have an RB67 and a Rolleiflex. The RB is reserved mostly for studio shooting when I want to do color, and the Rollei is for snap-shooting on the street. It's really a matter of horses for courses - when I'm traveling, especially someplace I've not been before, I take my Contax G2 outfit. Some day I will actually take my 14x17 camera on the road with me, but that will wait for a time when air travel either becomes reasonable again, or for a destination I can drive to.
