On Wednesday, Apple announced its newest iPhones: the iPhone 6s and the iPhone 6s Plus.
The biggest new feature? A pressure-sensitive touch screen called 3D Touch. Apps that support 3D Touch can be designed to respond differently depending on how much—or little—pressure you place on the screen.
Apple described two new multitouch gestures that will make use of 3D Touch. A light press, for example, will enable users to preview, or temporarily peek, into content, such as a new message in a list, or a photo that was just taken. If a user decides to take further action, a harder press will enable the user to pop into that piece of content.
It could be the biggest change to how apps are designed, and how you interact with your phone, since the iPhone was first introduced.
If you're an owner of an iPhone 6 or iPhone 6 plus, Apple's new devices might look the same. But as is typically the case with Apple's s-branded models, the company is packing some improved features into a form factor the same shape and size. The iPhone 6s still boasts a 4.7-inch screen, while the iPhone 6s Plus has a 5.5-inch screen.
Both iPhones' cameras are getting an upgrade. The rear camera has gone from an 8 megapixel camera sensor to a 12 megapixel camera, while the front-facing camera is getting a bump from 1.2 megapixels and to 5 megapixels. In both cases, there are video improvements: the rear camera can now shoot at 4K resolution, while the front-facing camera has gone from 720p to 1080p HD.
Apple also announced the addition of a new colour to its lineup, Rose Gold, which joins the existing options of Silver, Gold and Space Grey (Rose Gold first appeared on the Apple Watch). Each model will also be made from a more durable 7000 series aluminium—the same as was used on the Apple Watch as well.
The processor has received a bump too, and will use Apple's A9 architecture, which is apparently 78 percent faster than last year's iPhones at CPU tasks, and 90 percent faster at GPU tasks.
Oh, and if you're planning on migrating from an Android phone to an iPhone? Apple announced that it's released a migration app for Android users to do just that.
If you're in the US, pricing and configurations are the same as last year's models: $199, $299 and $399 for the iPhone 6s, and $299, $399, $499 for the iPhone 6s Plus, for 16GB, 32GB and 128GB models, respectively, on a two-year contract.
Apple also announced a yearly upgrade option for US retail customers, which will get you a new unlocked iPhone with AppleCare each year, starting at $32 per month.
Pre-orders start on September 12, and will be available in stores on September 25, while iOS 9 can be downloaded on September 16.
