Why are Chrome OS machines considered interchangeable?

Chrome OS machines are considered interchangeable primarily because most data is stored in the cloud. This cloud-centric design allows users to access their applications, files, and settings from any Chrome OS device, meaning they can switch between devices without losing their work or personal data. Since the majority of the user experience is tied to online services like Google Drive, Google Docs, and various web applications, the specific hardware of individual devices becomes less significant.

This means that regardless of the specific model of the Chrome OS machine a user is working on, they can easily pick up their tasks from where they left off on another device, fostering a seamless experience across different hardware. The focus on cloud storage ensures that users have consistent access to their resources regardless of the actual physical device in use.
