IDC 近期發(fā)布研究報(bào)告稱，今年全球手機(jī)廠商的手機(jī)出貨總量將會(huì)達(dá)到近 18 億部, 預(yù)計(jì)今年智能手機(jī)的出貨量將為 6.86 億部，比去年增長(zhǎng) 38.8%?，F(xiàn)今智能手機(jī)多樣化的功能，對(duì)越來越多的的用戶來說，都日益成為一種更具吸引力的選擇。

手機(jī)用戶從功能手機(jī)到智能手機(jī)的過渡期仍將持續(xù)進(jìn)行。在這個(gè)重要的變革時(shí)期，大聯(lián)大旗下世平集團(tuán)為推波助瀾而推出RockChip + Spreadtrum 3G 智能手機(jī)方案，期能帶給客戶更多吸引力的商機(jī)。
