Technology Review has an interview with Mats Lindoff, the CTO of Sony Ericsson:
Technology Review: Where do you see the cell phone’s biggest impacts in the next few years?
Mats Lindoff: In 2009 we estimate cell phone companies will sell over 800 million phones. With a six billion global population, that means every eighth person will buy a new cell phone every year. I think that is quite amazing. Think what other technology has had such influence — maybe electricity? TV is much less, Internet is much less, cars are much less. The Internet is a little piece of the cake compared to cell phones. I think half a billion people will, this year, make their first phone call on a cell phone.
