Thanks everyone for your replies. I was just curious.
I use MF almost all the time, primarily because it can't read my mind, and I like to control the exact focal point. All of my shooting is outdoors, often in the woods, and AF doesn't know the difference between a branch, leaf or even a blade of grass and the eye of a creature. The narrower the DOF, the more critical the focal point becomes. Despite the advances in AF, I'm still more reliable, accurate and most of the time faster than AF (if it hunts even once). But I've been shooting so long, my MF technique is almost mindless second nature.
Even when stopping down for a wide DOF for scenic and other shots, I still prefer MF to control the hyperfocal distance, and for these type of shots I have plenty of time to fiddle with the focus.
Personally, I don't find the viewfinders in digital cameras any harder to use than the old film SLRs, but I do find modern AF lens a little harder to focus manually (short throw and sloppy ring). Cheaper and kit lenses are almost impossible to focus manually, but the better lenses still have fairly smooth focus rings (especially Zeiss). I do see, however, less attention to smooth focus rings in the future, because the vast majority of the market could care less.
I don't miss the apature ring, because I can do the same thing with one of the wheels quicker, easier and with less movement.
