F10 vs E39
Ouch ... while I love my BMW, I would suggest before you make the iPad vs Kindle comparison, you take a look at Ford Electronics vs BMW. Even Bimmer magazine rated Ford higher. Go play with both and tell me why the BMW is "quality over specs". If nothing else, the Ford is far easier and more intuitive to use. No - I would not buy a Ford - just saying BMW is just a little behind the curve.
My $100 Garmin runs circles around the BMW Nav system in my F10 .. and my lifetime Garmin upgrade cost $39 vs. the $250 annual cost I was quoted at BMW ...
