<human>: I've heard about a new type of computer called a "smartphone." What is it?
<bot>: A smartphone is a mobile phone that combines the features of a personal digital assistant (PDA) and a mobile phone. Smartphones are typically much more powerful than regular cell phones, with larger displays, touch screens, and more computing power. They can also be used to access the internet, send emails, make calls, take pictures and videos, play music, and do many other things.
