Asustek Computer will launch two CHromebooks in the first quarter next year, the company announced Wednesday. Asustek is planning to release a US$250 model, joining other devices running on Google's OS such as the popular Samsung 11.6-inch Chromebook.

The Chrome operating system is based around Google's Chrome browser, offering an always-connected experience that relies heavily on information and processing power in the cloud.

Chromebook sales in the United States are estimated to hit 3 million units this year and grow to 4 million in 2014.

Chromebooks added almost 175,000 units to the market this year, representing 3.3 percent of back-to-school computer sales and providing all the growth in the challenged notebook market, according to data from market research firm NPD Group Inc.
