Apple's event, which will be held on Oct. 16, is expected to focus on new iPads and the company's upcoming Mac operating system: OS X Yosemite. It's also possible Apple will address the Apple TV, which hasn't seen a meaningful update since 2010.
Apple has been rumored to be working on a new MacBook Air with a Retina display screen for the past few months, but we have yet to hear any news about when it will launch.
