"Google's Chrome OS chiefs explain in Technology Review how most of the web-only OS's features flow from changing one core assumption of previous operating system designs. 'Operating systems today are centered on the idea that applications can be trusted to modify the system, and that users can be trusted to install applications that are trustworthy,' says Google VP Sundar Pichai. Chrome doesn't trust applications, or users — and neither can modify the system. Once users are banned from installing applications, or modifying the system security, usability, and more are improved, the Googlers claim."
