Google Chromium OS is all about the web. All apps are web apps. The entire experience takes place within the browser and there are no desktop applications. Users do not have to deal with installing, managing and updating programs. Chrome OS doesn't trust the applications you run. Each app is contained within a security sandbox making it harder for malware and viruses to infect your computer. Chrome OS barely trusts itself. Every time you restart your computer the operating system verifies the integrity of its code. If your system has been compromised, it is designed to fix itself with a reboot. You can go from turning on the computer to surfing the web in a few seconds. You will experience the fastest speed for Google Chrome OS as compared to any OS alive.
Google Chrome OS will be ready for consumers this time next year.

Does Chrome OS include a POP3/Imap email client, and can you save downloaded files to a USB memory stick?
