From the Pew Research Center:
From getting news to playing games to reading a book, Americans now have a plethora of devices to choose from in order to meet their technology-based needs. For each type of device, the demographic makeup of owners can vary widely, so this section looks at these differences.
Smartphone ownership continues to grow
The rise of the smartphone has had a major social, political and cultural impact. It has changed the way people reach their friends, obtain data and media, and share their lives. Fully 68% of adults now have a smartphone, nearly double the share that Pew Research Center measured in its first survey on smartphone ownership in mid-2011. At that point, 35% of adults had smartphones.

More than half of most demographic groups have a smartphone. Only those ages 65 and older (30% of whom own smartphones) and those who do not have a high school education (41% own smartphones) fall below majority ownership. On the other hand, those ages 18 to 49 and those in higher-income households are coming closer and closer to saturation adoption. There are no differences in smartphone ownership among different racial and ethnic groups.

Close to half of all Americans own a tablet
The share of Americans who own a tablet computer has risen tenfold since 2010. Today, 45% of U.S. adults own a tablet – a substantial increase since Pew Research Center began measuring tablet ownership in 2010. Then, only 4% of adults in the U.S. were tablet owners. Ownership, however, is statistically the same as it was in 2014.
Tablet ownership varies across a number of demographic groups. Younger adults and those from more affluent backgrounds are more likely to own the devices, and differences tied to educational attainment are particularly pronounced: 62% of college graduates have a tablet, compared with 35% of those with a high school diploma and 19% who have not completed high school. Additionally, whites are more likely than Hispanics to own a tablet computer, while tablet ownership among blacks is not statistically different from that of whites or Hispanics.

Popularity of e-readers declines
Some 19% of adults report owning an e-reader – a handheld device such as a Kindle or Nook primarily used for reading e-books. This is a sizable drop from early 2014, when 32% of adults owned this type of device. Ownership of e-readers is somewhat more common among women (22%) than men (15%). Whites are more likely than blacks and Hispanics to own an e-reading device, while ownership also tends to be higher among those who are more affluent and those with more education.

While PG prefers using an ereader for long-form text, in a world with $50 Fire tablets, ereaders are going to be more and more of a niche product.
However, a decline in ereader sales does not imply a decline in ebook sales. PG thinks the best thing for ebook sales is a device, like a smart phone, that readers always have nearby.
