Good news for Apple: cellular handset shipments grew 12% in 2010 to 1.5-billion units, according to Research and Markets (http://www.researchandmarkets.com). That’s in comparison with 2009’s negative 1.3% growth.

The research group predicts a strong, but more traditional growth in 2011 of 4.3%, but smartphones will continue to do better, growing 15.4% to the 318 million level this year. Though Samsung and Apple are growing faster, Nokia continues to be the leading handset vendor.

However, Nokia’s average handset selling price is among the lowest because of their huge share of the low-end markets in China, India and Africa. Nokia still reigns as the largest vendor of smartphones, but smartphone vendor Apple is catching up.

The cellphone continues to be the physical and market magnet that is pulling in the functionality of digital cameras, PDAs, MP3 players, GPS navigators, Wi-Fi, Bluetooth, AM/FM Radio, mobile TV, smart cards and fingerprint sensors. The mobile phone is quickly becoming the dominant market for virtually all of these functions.

And Apple, of course, is dominating this dominate market.
