Excerpt 1: Sales of e-readers surged during the Christmas holiday season, according to a Pew Research Center report, which showed that the number of adults in the United States who owned tablets nearly doubled from mid-December to early January. Excerpt 2: Apple, based in Cupertino, California, controls 73 percent of the market, while Samsung Electronics Co. , Sony Corp. and Toshiba Corp. are among companies making constant improvements on table without bringing services that cut into the market share, Sarah Rotman Epps, an analyst at Forrester, said in the report. Excerpt 3: Under Squares year-long pilot program, an iPad would be installed in the space where Taxi TVs currently sit, and the driver would have an iPhone to process credit-card payments. The technology would allow drivers to accept a passengers card at any point during the ride, then enter the amount later. The system charges drivers less in credit card transaction fees than the current rates. Excerpt 4: When Apple introduced the iPad tablet computer in 2010, it was doing what it likes to do best: creating a new category to dominate, as it had done with the iPod and iPhone. By the end of the year, the company had sold nearly 15 million iPads, generating about $9.5 billion in revenue. Just two years later, the chief executive of Apple, Timothy D. Cook, has a prediction: the day will come when tablet devices like the Apple iPad outsell traditional personal computers. Excerpt 5: Apple has made its first attempt to quantify how many American jobs can be credited to the sale of its iPads and other products, a group that includes the Apple engineers who design the devices and the drivers who deliver them—even the people who build the trucks that get them there. On Friday, the company published the results of a study it commissioned saying that it had "created or supported" 514, 000 American jobs. The study is an effort to show that Apples benefit to the American job market goes far beyond the 47, 000 people it directly employs here. Excerpt 6: People who read e-books on tablets like the iPad are realizing that while a book on a black-and-white Kindle is straightforward and immersive, a tablet offers a menu of distractions that can fragment the reading experience, or stop it in its tracks. E-mail lurks tantalizingly within reach. Looking up a tricky or unknown fact in the book is easily accomplished through a Google search. And if a book starts to drag, giving up in it to stream a movie over Netflix or scroll through your Twitter feed is only a few taps away.
