Mark Gurman, reporting for Bloomberg: Apple is ready to take on Amazon.com in the digital book market again, years after regulators forced the iPhone maker to back down from an earlier effort to challenge the e-commerce giant's lead. Apple is working on a redesigned version of its iBooks e-book reading application for iPhones and iPads and has hired an executive from Amazon to help. The new app, due to be released in coming months, will include a simpler interface that better highlights books currently being read and a redesigned digital book store that looks more like the new App Store launched last year, according to people familiar with its development. The revamped app in testing includes a new section called Reading Now and a dedicated tab for audio books, the people said. Apple released an early version of its iOS 11.3 mobile operating system update to developers on Wednesday, providing a hint that the new e-books app is on the way. The app is now simply called "Books," rather than "iBooks," according to the update.
