The much heralded post-PC era may take quite a while to arrive, if new research from Nielsen is accurate. The report, presented today at the paidContent Mobile conference, shows that fewer than 5% of people in the US own a tablet.
By comparison, 36% of respondents in the Nielsen study said that they owned a smartphone, and 13% owned a media player. In addition to relatively low penetration levels, the tablet market is also growing more slowly than some other markets. The number of e-books owned, for example, tripled in the year between Q1 2010 and Q1 2011.
