Apple has unveiled a new tablet that is bigger and more powerful than its earlier versions.

The company says the iPad Pro is as powerful as many laptop and desktop computers.

To cement its appeal to professionals, Apple is selling it alongside a stylus and snap-on keyboard.

The move is an attempt to reverse declining iPad sales.

BBC North America technology reporter Dave Lee tried out the new device at Apple's launch event in San Francisco.
