As affordable tablets make their way to the market, overall tablet ownership continues to grow. Pew Internet reports that tablet ownership increased to 34% in 2013 among U.S. adults over the age of 16. When adding eReaders into the mix, the ownership number for slates shoots up to 43%. This report shows a 10% jump over last year’s numbers, which contained the biggest year-over-year increase in tablet and eReader ownership to date. These numbers should be especially encouraging for Amazon and Samsung, both of which recently released new tablets and e-book readers, as well as Apple, which is planning to unveil a new tablet lineup next week.
