Google has announced new computers running on its Chrome operating system.

The Samsung-manufactured laptop and desktop PCs include processors based on Intel's Sandy Bridge technology, addressing criticism that the launch models were underpowered.

Chrome-based computers run all their applications through the firm's web browser and store their files online.

Google has not released sales numbers for the previous range, but analysts said demand had been very low.

Tech consultants IDC said that 50,000 Chromebooks had shipped in the US in the first three months of the year in a market that had absorbed about 10 million laptops over the same period.

An earlier study by Gartner suggested there would be fewer than 300,000 Chromebooks sold worldwide this year.
