Over the next few years, tablet devices will enjoy double-digit growth and become a primary computing device for millions of users in the US, a study by sales analysis firm eMarketer claims. The company points to the fact that more than 33 million use a tablet device at least monthly, a gain of more than 158 percent compared to the year the iPad debuted and mainstreamed the tablet market. By 2014, more than 35 percent of all US internet users will be on tablets, the study says.
