Which device uses convergence?

I'm curious to know, which device is it that employs the concept of convergence? Convergence, in the realm of technology, often refers to the integration of various functions or technologies into a single device. It's fascinating to ponder which device has taken this approach, combining multiple features or capabilities to offer a more streamlined and comprehensive user experience. Could it be a smartphone, which has integrated cameras, GPS, and countless other features? Or perhaps it's a device designed for a specific industry, like healthcare or aviation, that leverages convergence to improve efficiency and functionality. I'm eager to hear your thoughts on which device utilizes convergence in an innovative and impactful way.
