Continuing that path I'd say: Tesla gets software right. Way better than what I've seen in other cars.
But what stops that iPhone metaphor for me is Design, Materials and Finish. Apple Products look and feel like luxury. Where as Tesla only achieves that on the software side - and in your pocket.
At the risk of sounding like a nationalistic asshole, Teslas look very American - i.e., a mix of cheap and tacky. Put a 5 series bmw next to it - two different leagues really. I want to root for Tesla, and I'd buy one if I could park it somewhere where I could charge it, but I don't think they're doing great in the looks department, especially not to Europeans.
