Chromebooks are, in every sense of the word, laptops; yet, they run Google's Chrome OS rather than Apple's macOS or Microsoft's Windows. Chrome OS is a browser-based operating system that was primarily developed with users who are always connected to the internet in mind. Windows and Mac OS devices, on the other hand, are oriented more toward users who combine online and offline work, and they let you install more software locally on your laptop. This gives you more flexibility in how you work.
