The iPhone was first launched ten years ago and since its launch, more and more people have switched over to smartphones each year. If you take a look at this infographic The Importance of a Responsive Website, you will see the figures for mobile and smartphone users across the world. In the UK, 97% of the population (aged 16+) own mobile phones and of that figure, 61% have smartphones. South Korea is even more advanced with 99% having mobiles and 67% with smartphones. Those are quite huge figures and show just how far the world moves on in a decade.
Over the next few years, even more people will be accessing the internet through smartphones, so make sure that your website is set up to provide a good experience in terms of web hosting performance and being mobile friendly.
