Apple has launched the long-rumored iPad Pro today. With its 12.9-inch Retina screen offering 2732 x 2048 resolution the new model is the largest in the iPad line-up. The large screen makes use of some of the new iOS9 features such as multitasking and picture-in-picture and allows for the use of a full-size virtual keyboard.

Inside a new A9X processor offers 1.8 times the power of the A8 chip in the iPad Air 2 and 2 times the graphics performance. Apple claims it'll let you edit three 4K video streams at the same time. Despite the large screen and increased performance, according to Apple the iPad Pro still offers 10 hours of battery life. It's also 6.9mm thin.

A new four-speaker stereo system offers three times the volume of the iPad Air 2 and dynamically adjusts to the way the user is holding the tablet. For image capture there is an Apple iSight 8MP camera on the back and a FaceTime HD camera for video chatting and the occasional selfie on the front.

The iPad Pro also comes with a couple of optional accessories that can help improve productivity. The new Smart Keyboard connects via a new magnetic Smart Connector interface and also serves as a cover. It will be available for $169. The Apple Pencil is a $99 pressure-sensitive stylus which is also capable of detecting tilt for broadened or shaded strokes when drawing or writing. It charges via a Lighting Connector that attaches to the iPad Pro.  

In its presentation Apple also showcased a range of new software applications that take advantage of the iPad Pro's features. Among others Adobe demoed its new suite of apps for the iPad including Photoshop Fix which lets you edit images of up to 50MP size using the Apple Pencil. The app features facial detection in its retouching engine which allows for the isolation of facial features such as the lips. The iPad Pro will be available silver, gold and space grey, starting at $799 for the 32GB version. A 128GB version will set you back $949 while the LTE-enabled iPad Pro will be $1079.
