Apple (AAPL) and Research In Motion (RIMM) will continue to sleep on the emerging “phablet” market in 2013, according to a new report. Android vendors including Samsung (005930), HTC (2498) and Sony (SNE) will capitalize on strong demand for 5-inch smartphones in 2013, Digitimes claims. Meanwhile Apple, RIM and Nokia (NOK) have no plans for 5-inch smartphones this year according to the site’s unnamed industry sources. How big is the opportunity these companies are missing? Digitimes cites research suggesting 60.4 million smartphones with screens measuring 5 inches or more will ship this year, and that figure will climb to 146 million units in 2016.
