When the first two features are more like commercials for products that will be released in 2011, it is interesting to find out what is that Chrome Web Store, that would be similar to an Apple Store, where you can buy applications "cloud" (for use online only) for the Chrome future OS, and also for the Google Chrome browser. Even if you can not buy applications, you can still download and install the free ones and, for the moment, there is still a bit wrong. By accessing the Web Store of Chrome you can browse and extensions for the browser you already know, both graphical themes for the browser, and new applications, divided into categories, highlighting the most popular. Obviously I have not tried everything, but after a few installed, you may notice that they are nothing but bookmarks, or link to websites that are added but not in the bookmarks bar on the front page of Google Chrome. When you open a new blank tab in your browser, you can see these links at the top of the window.
