IMO the biggest problem is that it's a race to the bottom. If your biggest selling point is your low price, and you're essentially selling a commodity product, your customers will leave as soon as another company undercuts you. Apple thinks very hard about every product they release. They are extremely careful not to put out a product that could tarnish their brand. They'd rather put out one AAA device than 5 B+ devices. As a result, they have earned a reputation that MS, Samsung, Motorola etc. would kill for. People get excited when Apple announces something new. It's not because Apple fans are mindless sheep. It's because Apple has earned a reputation for only putting out great products. Along with that come customers who are willing to spend a little more for quality. Those are coincidentally the same ones who actually pay money for apps and content. Could Samsung do that? I'd say yes, but it would take them years to build up the reputation for quality that Apple has.
