The first laptop was produced in 1981 but it took more than a decade of development for the designs to approach current (2016) levels of portability and capacity, and hence uptake. Apple produced the first smartphone (the iPhone) in 2007 and the first tablet (the iPad) in 2010. In 2015 there were 4.43 billion mobile phone (cellphone) users in the world, of which 2.6 billion had smartphones. In the US, 45% owned a tablet computer in 2014 and 92% owned a mobile phone; for younger adults aged 18–29, only 2% didn’t own a mobile phone and 50% had tablets.
