It is interesting to note that a Linux based notebook, the Samsung Chromebook, has been listed as the top selling laptop computer at amazon.com, pushing all Windows and MacOS based laptops to lower ranks.
Chromebooks are intended to offer a new type of user experience by eliminating many of the hassles typically associated with PCs and notebook computers that run traditional operating systems. For example it cuts down start-up time to a few seconds, immediately being connected to the Internet, eliminates the need to install and maintain software, and minimizes the frequency of recharging the battery.
This is accomplished by using the Linux-based Chrome OS to shift much of the maintenance of software and data to the web. Software on the Chromebooks will be automatically updated and your data automatically backed up on the web.
Samsung's basic model includes Wi-Fi, 2 GB RAM, a 16 GB solid state drive, and a 1.7 GHz Exynos 5200 processor. It has a 1366 x 768 pixel 11.6 inch display, 2 USB ports, a built-in webcam, and weighs in at 2.4 pounds.
The central application of the Chromebook is the Chrome browser which kind of takes the role of the operating system and the desktop environment. The opening tab of the browser contains links for YouTube, Google Maps, Gmail, the Chrome Web Store, Scatchpad, and a couple of games.
