Thanks for the post gives me something to consider when my MY13 lease is up in two years. And don't feel bad about the iDrive touch as (1) most people who have it are not impressed and (2) my $150k Alpina B7 delivered 2 weeks ago doesn't have it either although the brand new 750li on the lot has it with the new LCD dash.
