If you just bought a new 60" tv and while hooking it up to your DVR, Blueray, Apple TV, home theater system, you put a 4" scratch on the back of it, would you really complain in the manufacturer's forums that it's a horrible design?
Your car vs phone example holds a lot less water because of the price difference. If you're paying 50-100 times more for something, you hold it to a higher standard.
If someone isn't happy with their purchase they can just return it for a full refund. I'm sure there is a line of people that would be willing to buy it.
