Apple downsizes: Tech giant launches £359 4-inch iPhone SE, a cut-price Watch and a smaller, more powerful iPad Pro

The phone (range pictured left with Apple's Greg Joswiak), which is the first 4-inch phone to be unveiled since the iPhone 5s and 5c, was unveiled in San Francisco alongside a 9.7-inch iPad Pro (top right with Apple's Phil Schiller). 

Both devices will be available to order from the 24 March. 

Apple's boss Tim Cook opened the event by revealing there are now one billion active Apple devices globally, and he revealed the Watch price - with its new straps (pictured bottom right) will now be $299 - down from $349.
