Apple Inc.'s  (AAPL) - Get Report newest operating system, iOS 11, isn't supposed to officially launch until Sept. 19, but some users were already being prompted to update to the latest version on Thursday. 

iOS 11 promises a slew of shiny new features for the iPhone and the iPad, including support for ARKit, Apple's suite of tools that lets developers create augmented reality-powered apps. Apple first announced iOS 11 at its Worldwide Developers Conference in June, releasing a beta version for those brave enough to download it (and potentially lose all their apps and data).

At its big iPhone unveiling event on Tuesday, Apple said that its latest mobile operating system wouldn't be available until Sept. 19; however, several users reported on Twitter on Thursday that they were already able to update to iOS 11. 

iOS 11 has some cool updates to the iPhone, like a new control center, lock screen and iMessage app features, all of which are meant to make users' lives easier.

But Apple has much bigger plans for iOS 11 on the iPad. With the new iOS update, the tech giant is making the case for why the iPad should replace the traditional laptop. It remains to be seen whether Apple will succeed, but new features such as the Files app and multitasking capabilities might push consumers that much closer to ditching their PC or Mac. 

Here's some of the most useful features coming to the iPhone and iPad in iOS 11: 

1. Interacting with Siri just got easier


Apple's Siri voice assistant will now be a lot more intuitive. It can give follow-up questions to queries, translates words to multiple languages and suggests things you might like based on what you're doing, like music or news. Siri's voice will also sound a bit more natural and human-like thanks to a small update.

Users can also type questions to Siri without speaking, which might seem like a step backward, but could actually prove to be handy if you're in a place where talking out loud is inconvenient.
