We first talked about the $10 Laptop concept back in May 2007 when it was considered merely a piece of fiction. The topic is on fire again and according to a report by Infoworld, India is carrying out deep research on commercial development of such low-cost laptops.
The concept came out last year when India refused to sign up for the OLPC (One Laptop Per Child) program which is currently the most successful running low-cost laptop program around the world.
No information about the specifications of the laptop has been revealed yet but I would be surprised if it is not running Ubuntu Linux, which is currently the most easy-to-use and free operating system.
The main hurdle faced by the $10 laptop concept is the low manufacturing cost which is highly unlikley to be attained. However considering India and the advancement in its technological sector, $10 laptop may soon become reality.
