I read a lot of negative opinions about i-drive from car mags and was expecting the i-drive system to be complicated as all the critics say. However, i had the chance to test drive a 7 series with the i-drive, and it seemed quite intuitive to me...the controller works a lot like a mouse, and its all select and click basics that any one who can operate a basic computer should be able to use. I personally like it...i think after getting used to it after i would be able to memorize the motions to operate all the functions without even looking down. And it makes the interior look a whole lot cleaner by minimizing the buttons and dials needed. have you tried it and what do you think?
