I probably should have read a bit more thoroughly. Though, after using digital cameras with only a display and very poor optical viewfinders, going back to an SLR was shear joy. There is nothing that connects you to the act of taking a photo like having your eye up to a viewfinder, seeing the whole image, nothing but the image, and blocking out the distractions and glare.
I think you see an image that is closer to what the photo will be.
You are one with the camera, Grasshopper.
