Growth of the worldwide converged mobile device market (commonly referred to as smartphones) more than doubled that of the overall mobile phone market in the first quarter, a sign the segment is in high-growth mode again. According to the International Data Corporation (IDC) Worldwide Quarterly Mobile Phone Tracker, vendors shipped a total of 54.7 million units in the first quarter of 2010 (1Q10), up 56.7% from the same quarter a year ago. In contrast, the overall mobile phone market grew 21.7%. Converged mobile devices accounted for 18.8% of all mobile phones shipped in 1Q10, up slightly from 14.4% in 1Q09.
The smartphone market's growth is impressive too when contrasted to the 38% growth in the fourth quarter, which is typically the strongest of the year. This demonstrates the tremendous potential of the market and the depths to which it plunged in the first quarter of last year.
