Don't forget: iOS 11 was designed for the iPhone X

iOS 11 has arrived (here's how to download it). And it was clearly designed to shine on the iPhone X (and, sure, the iPhone 8 and 8 Plus). But it will work on a bunch of older devices, too: if you have an iPhone 5S or later, a fifth-generation iPad or iPad Mini 2 ($234.00 at Amazon Marketplace) or later or a sixth-generation iPod Touch, you, too, can upgrade. 

Some of iOS 11's new features include:

Loads of AR applications 

Editable Live Photos

New Control Center

Venmo-style Apple Pay payments

More configurable storage space

Distraction-free driving

Improve battery life
