The search giant Google has presented what they call the Chromebook at the Google I/O 2011 conference. There are already portable machines from Samsung and Acer with Google Chrome OS preinstalled, which will be made available soon. This means that Google has launched an attack on a market dominated by Microsoft and Apple.

“These are not typical notebooks,” explained Google vice presidents Linus Upson and Sundar Pichai in a post to the company’s blog. “With a Chromebook you won’t wait minutes for your computer to boot and browser to start. You’ll be reading your email in seconds. Thanks to automatic updates the software on your Chromebook will get faster over time.”

According to Google the Chromebook will start up in just a matter of seconds (8 seconds or faster), and the preinstalled software will be automatically updated. The core of the Chromebook is the Google Chrome browser, since Google believes that most users spend most of their time online anyway, and therefore the operating system is very much based on this fact.

The Chromebook is said to have the battery capacity of around 24 hours, and it comes with built-in 3G (optional). The machine already has many layers of security built in, so there is no need for additional security software. They will also be able to offer some kind of offline capability by including a file manager.

The machines are scheduled to be available on Wednesday June 15 in the United States, Britain, France, Germany, Netherlands, Italy and Spain. More countries will follow later. The pricing is currently set to $349.
