Today's Moto E announcement demonstrates exactly what Lenovo sees in Motorola and illuminates one major reason why purchasing the cellular device company makes so much sense. The affordable phone, at $129 unlocked, targets people who have yet to buy smartphones, but own so-called dumb ones. They make up a huge market, much of it in Lenovo's backyard and largely ignored by Apple. Smartphones accounted for 62.7 percent of mobile handset shipments during first quarter, up from 50.7 percent a year earlier, according to IDC. But as sales shift to smartphones they also slow in many mature markets, such as the United States where the install base nips 50 percent. Looking ahead, the higher-hanging sales will be the lowest-cost phones, where unlocked matters in many emerging markets, particularly Asia. Samsung is the global smartphone leader (30.2 percent market share; IDC), having gobbled up many markets once dominated by Nokia.
