Chromebook

A Chromebook is a laptop or netbook that runs Google Chrome OS as its operating system. The devices comprise a distinct class of personal computer falling between a pure cloud client and traditional laptop. The first devices for sale, by Acer and Samsung, were announced at the Google I/O conference in May 2011, and began shipping on June 15th, 2011. Now there are many devices for sale from many different manufacturers.

Design
Chromebooks are shipped with Chrome OS, which uses the Linux kernel, and the Google Chrome web browser with several other features developed specifically for the OS. Users can run web apps, chrome extensions, Android apps, Linux apps, and soon, there might be support for Windows apps. Google claims that a multi-layer security architecture eliminates the need for anti-virus software.

Support for many USB devices such as cameras, mice, external keyboards and flash drives is included, utilizing a feature similar to plug-and-play on other operating systems. Chromebooks have a specialized keyboard complete with buttons for opening and controlling multiple browser windows, as well as a search button, which replaces the caps lock key (which can still be activated through a keyboard shortcut).

Google has also put a large amount of effort into making the operating system more functional when not connected to the internet. As part of this effort, Google Drive has been largely integrated into the operating system. The service allows for document editing when offline, and then uploads it back to Google Drive as soon as the device is connected to the internet again. Additionally, Google has made it possible for developers to add offline functionality to their applications. Overall, the operating system is far more functional without an internet connection than it was when first released.

Models
Google developed the first Chromebook, the Cr-48, as a prototype machine. The first commercial Chromebooks were produced by Samsung and Acer. Since then, both companies have updated their models. HP and Google have also made their own Chromebooks, as well. A complete list of Chromebooks can found at List of devices running Chrome OS.

Trademark dispute
In June 2010, ISYS Technologies, based in Salt Lake City, sued Google in a Utah district court, claiming rights to the name "Chromium", and, by default, Chromebook and Chromebox. The suit sought to stop Google and its hardware and marketing partners from selling Chromebooks.
