"Smartphone centricity continues to be the hallmark of the mobile phone market," says Ramon Llamas, senior research analyst with IDC's Mobile Phone Technology and Trends team. "Two years ago, smartphones comprised just a small portion of overall shipments among the leading vendors. Today, that proportion has grown considerably, thanks in large part to LG, Motorola, Samsung, and Sony Ericsson making Android smartphones a priority. At the same time, the growing presence of companies focused exclusively on the smartphone market - Apple, HTC, and RIM - also demonstrate the impact that smartphones have had on the mobile phone market as a whole."
