I've only used the iDrive in the 5 series so I can't compare it to the other systems, but I find it easy to use. I learned how to use in just a 30 minute test drive. Now that I've lived with it for 20 months I still find it easy to use. Like warot says, I don't use it much. I have the audio source and mute functions programmed into the steering wheel buttons. With those buttons and the volume and channel buttons also on the steering wheel you don't have to touch the iDrive for the radio once the presets are set. The climate control is on the dash so no iDrive needed for that either.

As far as Autolies is concerned I can't take anything they say about the S-Class seriously. They've been talking up the new S-Class for a couple of years, ever since they somehow got a sneak peak at it a couple of years ago. They've been saying it is the greatest thing since sliced bread ever since. While the S-Class may be great, Autolies can't afford to say anything negative about it because it would make them look bad.

MMI is the best, that's coming from a person that has used all three.

You've used COMAND III? When did you get a chance to drive a W221? You said you were gonna post a review if you drove one.

I played with it at the Athens International Motor Show. I used it for about 10 mins. and i can say it was pretty easy and funny to use. I am not sure about one thing though. Is it easy and safe to use it while driving?

none of these systems are safe... you still have to pay attention to what you are doing instead of paying attention to the road. Like I said before, most of the stuff on the Idrive you use before you set off rather than when you are driving. I'm sure the other 2 are the same.
