The iPhone at 15 -- what is its legacy and its future?

In 2007, Steve Jobs took to the stage to introduce what he called a “revolutionary new product”. This week 15 years ago, the first iPhone went on sale. Is it still an all-conquering device? What might September's iPhone 14 bring? And can the iconic smartphone stay at the heart of Apple’s world, or will smart glasses and cars become the company's new focus? Joining technology editor Adrian Weckler to discuss all of this is someone who was at the original launch – Stuart Miles, the founder and CEO of Pocket-lint.com.
