A new Pew research survey of U.S. adults conducted in May, 2011 shows that ownership of electronic readers such as the Amazon Kindle or The Barnes & Noble Nook is now at 12 percent. The ownership of e-readers doubled from six months prior when it was 6 percent. The adoption of e-readers continues to outpace tablets such as the iPad and Motorola Xoom. Only 8 percent of respondents said they won a tablet, compared to 5 percent six months earlier. So tablet ownership seems to be growing at a slower pace.
