Some interesting stats about smart phone sales…
Worldwide sales of smart phones grew 30 percent in the fourth quarter of 2009 to 53 million phones , according to researcher Strategy Analytics.
Nokia led market volumes, ahead of Research in Motion (RIM) and Apple, and shipped 20.8 million smart phones during the fourth quarter - up 38% from one year ago.
I also found an interesting chart from ComScore about U.S. smartphone platform share , or installed base – representing both existing devices and new sales during each period, not just new sales.
