Then again, on our fleet of 737-800's we have to disconnect the autopilot by 1000' agl and land using our "Heads Up Display" which allows us to go down to 600 RVR... and we actually hand fly the landing and touchdown/rollout.
The first time you land hand flying at 600 RVR you think this is crazy, but after about 2 approaches, the HUD makes it very, very capable and comfortable.
