I saw a special the other day on CNBC called BMW: A Driving Obsession and it really opened my eyes as to the incredible attention to detail that a car maker like BMW has when building a car. Just check out how much effort they spend just on getting the little sounds the car makes just right at 16:00 and 20:55 http://www.youtube.com/watch?feature=player_embedded&v=O... If that's how much time they spend on just the sounds, it's not difficult to imagine how much effort they put into everything else. Heck, at 29:03 one of the BMW designers even says they use Apple products as inspiration.
Now, if you agree that iOS is that much more polished than Android, I think this is a pretty accurate metaphor and any class distinction Topolsky inferred from Siegler's Gruber's comments are of his own creation. I doubt Gruber and Siegler would ever admit to it even if it were the case so I guess we'll never know.
