First look at India's Aakash 2 tablet computer
The latest version of the world's cheapest tablet device has been unveiled in India. Aakash 2, which will sell for 2,263 Indian Rupees ($40), has improved specifications.
The Indian government hopes it will help improve education and internet access across the country. However, the initial run of the Aakash project was beset by distribution problems.
The BBC's Rajini Vaidyanathan had a first look at the new tablet, with Professor Deepak Phatak of Mumbai's Indian Institute of Technology.
