Apple has posted a pair of new job listings in the last week that suggest the company will be making further use of plastics in future products, supporting rumors that have circulated about the company producing a lower-cost iPhone that would prominently feature plastic in the body of the device. The job listings themselves suggest Apple is looking more for engineers that can help it push forward in "non-traditional" ways of using, shaping and controlling the material on behalf of suppliers as well as itself.
