The new Apple iPad Air and iPad Mini

Apple just unveiled two new iPads, the iPad Air and the iPad mini with Retina. 

The iPad Air is the new name for Apple's full-sized iPad. It is significantly thinner at 7.5 millimetres, and incredibly lighter than the previous model. It also has an A7 chip for better CPU performance, graphics performance, and battery life.

Meanwhile, the iPad mini also got an upgrade. It now has a sharp Retina display like the iPhone and iPad, and sports Apple's new mobile operating system, iOS 7. The iPad mini comes with tons of built-in apps. Tools like iPhoto, iMovie, GarageBand, Pages, Numbers, and Keynote are now all available for free. Apple says the iPad mini delivers twice the Wi-Fi performance of the last model.

The iPad Air will start at $499 and goes on sale November 1. The iPad mini will cost $399.
