Apple is planning to reveal iPad updates at an invitation-only event later this month, the technology news website AllThingsD reported Tuesday. The next-generation iPad is expected to be thinner than its predecessor and boast improved camera capabilities. An upgraded version of the iPad mini is likely to list an improved screen among its features. The event will be held on October 22, according to AllThingsD. Apple declined to comment on the report, which cited unnamed sources. The iPad remains the largest-selling tablet, according to surveys, but its market share is being eroded by rivals using the Google Android operating system. Apple was expected to discuss its computer operating system and its laptop line at the event, timed for the start of the year-end holiday shopping season. Apple is coming off a wildly successful launch of two new iPhone models last month. The California firm said it sold a record nine million iPhones in the three days after launching two new versions of the smartphone.
