You may be surprised on how much more consumers will pay for a BMG computer or phone, etc. Then APPLE can have a trade in value that will increase the incentive. APPLE seems to be going towards different quality items. They will offer plastic, aluminum and BMG.. IMO. The BMG will be a status symbol for companies, perhaps even offering a unique "Logo" on it.
plastic? liquidmetal will substitute for more than just plastic. aluminum for example. also if BMG is more durable, it cuts the cost of warranty repair costs. it also should decrease the number of manufacturing steps, as well as accuracy and precision of robotic assembly. $^)
