I also bind by machine, and I'm quite skilled at it, if I do say so myself. I can catch just the edge of binding on the back side, and hide the stitching in the ditch on the front side. It's very old fashioned to think that good bindings have to be hand stitched.
For those that enjoy hand stitching a binding... more power to you! I will do it by machine.
The only hand work I do is the little blind sts in the corners to keep the miters in place. Very quick.
