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?

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.
