The smartphone is 20 years old, believe it or not
The breakneck pace of change in the smartphone world is well known: Since the iPhone catalysed popular demand in 2007, development has been moving faster and faster, to the point where devices are out of date mere months after their release. However, this wasn't always the case. In fact, according to some estimates, the smartphone is actually all of 20 years old, as of last Friday.
