I agree with your point.. however, the new iDrive is probably ahead of everybody in many aspects.. Camera, HD Based NAVI, screen resolution, Entertainment options (including music storage), access speed (browsing through menus), intuitiveness..

overall, i give it 5 stars.. i might change my mind when i get my car a in a couple of weeks, but i speak from experience of owning/using the MKIV NAVI, latest Acura MDX, 08 X5, Infiniti NAVI..
