Are books the new killer app?

A new study by the Pew Internet and American Life Project shows that e-reader ownership among U.S. adults doubled from 6% to 12% between November 2010 and May 2011. This marks the first time ownership of devices such as the Kindle and Nook has reached double digits.

[....] According to the study, 22% of households with college graduates now own an e-reader, up from 8% in November 2010. Similarly, 24% of households with income over $75,000 now own an e-reader.
