Chromebook devices from Acer, HP and Samsung are rolling out today in six countries, Google said.

The countries where the laptops will be available are Australia, Canada, France, Germany, Ireland, and the Netherlands, the company said.

The rollout is however not uniform across these countries. In Australia, for example, the Samsung Chromebook and the Acer Chromebook are now available from select stores while the HP Chromebook is still on its way.

The Chromebooks are also getting delivered to businesses and schools in the countries "to help improve computing for organisations," said Caesar Sengupta, product management director.

More than 2,000 schools are now using Chromebooks for education, Google said. Businesses around the world are also using Chromebooks "where they need greater security and increased shareability," it added.

Google launched a Chromebook from Samsung in the UK and US in October, with pre-orders and later sales through, Best Buy, PC World and other retailers. The laptop is an attempt by Google to attract users to cloud computing.

"It's been rewarding to work with our partners to make Chromebooks available to more people around the world, and we're looking forward to bringing Chromebooks to even more countries in the months to come," Sengupta said.

HP announced in February the availability of its Pavilion laptop running the Chrome operating system, to try to improve laptop sales by offering an alternative to Microsoft's Windows operating system. Google also launched in February the Chromebook Pixel, a high-end performance version of the laptop.
