How often do you crop?

Besides square, I crop to 4X5 ratio. I rarely print a full image from a 2X3 ratio format camera. I was always a big fan of the square medium format cameras or the 6X4.5 format. It's probably one reason I gravitated to the olympus 4/3 cameras. Given how I crop, an aps-c sensor doesn't have a lot more usable area as I crop the sides off anyway.
