The tablet segment of the industry, which was re=invented by Apple, has yet to begin reaching critical mass.
Here is another mini article I found.
What is interesting about this article is that there is not bashing, which proves that the author is not "on the take".
The Truth About: Smartphone vs Tablet Usage
While smartphones have reached critical mass, tablets are poised to do the same soon. As a form factor, tablets simultaneously take a step toward the living room and the workplace. For consumers, these devices are multimedia machines, offering a glimpse into how consumers might one day accept connected television. For workers, IT departments are already reacting to the “Bring Your Own Device” wave changing the modern workforce. According to Forrester, 12% of workers already use a tablet at work.
The stakes are high. According to its latest earnings call, more than one out of every three Apple smart devices sold during the last quarter was a tablet, 14 million iPads versus about 27 million iPhones. And with the announcement of the lower-priced iPad mini, more directly competing with Amazon’s Kindle Fire HD, Google’s Nexus 7 and Samsung’s Galaxy Tab 2, we anticipate this ratio to increase more toward tablets during the holiday season.
This report focuses on how consumer demographics and behavior vary between smartphones and tablets. Taking a snapshot in September 2012 from Flurry Analytics, that totaled more than 6 billion application sessions across approximately 500 million smart devices, Flurry provides a comprehensive comparison between smartphones and tablets, spanning age, gender, time of day usage, category usage and engagement metrics. For age and gender comparisons, Flurry leverages a panel of more than 30 million consumers who have opted-in to share demographic data.
