Actually, Honda/Acura has full iPod integration with ID3 tags displayed on the head unit or nav screen plus steering wheel and voice control of the iPod (only one to have it).
And yes, Mercedes, VW, Audi and Toyota/Scion have full integration.
I can understand the original poster's opinion. Although I am happy with my 3 series, I do wish there was more technology for the user experience available (e.g. better nav, 6 disc in-dash CD player, iPod integration, better human interface in general). Although the driving experience is great and 2nd to none, the whole car experience could be improved.
