The Operating system, chrome os has many neat features, but one feature in particular is the web apps. Since Chrome os is a web based operating system it uses web apps which can be installed via the chrome web store. In the webstore you can get games and apps from many different categories.
In the webstore you can get both apps and extensions and also you can get themes to customize your chrome os netbook. Web apps can help you when you working on documents and also there are some for music and other things you might use. Web apps update automatically when new versions are released that is really helpful. I think the web apps are really neat I think.
