Actually, it's an apt comparison. Not in the way he/she intended though. Android is exactly like Fiat. They have something for everybody. From the lowly Fiat 500 to a stable full of Ferraris and everything in between. And that's the point. Something for everybody.
Apple is less Aston Martin and more like BMW. Solid, reliable and exceptionally well performing machines. They sell well and make the company lots of profit. But there is an entry threshold.
The big question is whether this will hold true or whether this is where Apple wants to be. People seem to cite this model often (Apple as high price, high margin, the competition as low price, low margin). Yet, Apple does everything in its power to get carriers to sell the iPhone as cheaply as other handsets. And remember how much people expected them to sell the iPad for? And the shock when then price was announced? Apple still has the best margins in the business. But they aren't the high priced distributor that they are in the computing game.
I am skeptical whether Apple doesn't want at least some magical threshold of market share. For one, market share is essential to the viability of the platform in the mobile space. Nobody's going to make apps for you, if your platform isn't popular. And with the iPhone being a giant app launcher, that's a big deal.
