Human: I'd like to learn more about the different types of cell phones available. Assistant: 
There are many different types of cell phones available, and they all have different features depending on their purpose. Smartphones are typically larger and more feature-rich than basic phones, while budget phones offer lower cost but still provide essential functions such as calling and texting. Phablets combine the features of a smartphone with those of a tablet computer, providing users with an even bigger display and more functionality. Finally, there are ruggedized phones designed for outdoor use, which can withstand harsh weather conditions and drops.
