"Your apps, games, photos, music, movies and documents will be accessible wherever you are and you won't need to worry about losing your computer or forgetting to back up files," reads a statement on the official Google blog.

Computer makers Samsung and Acer will manufacture the Chromebooks, which will be available through Amazon and Best Buy.
