Reuters reports that the One Laptop Per Child Foundation has hiked prices to $188 per device.

The nonprofit group has been working on the OLPC project - to provide kids in developing countries with viable, affordable and portable computing solution - has been developing the product, named "XO" for years.

Originally planned to cost $100 per unit, back in May the group announced the price would rise to $176, while the latest pricing announcement by spokesperson George Snell now puts the tag at $188.

The laptop, to be bought by governments and then distributed to children, is planned to go into full-scale production in October.

Despite reports earlier this year suggesting millions of pre-orders, the group will not confirm level of interest in the product: "We are not disclosing any orders until we have a final computer", Snell said. "We are in talks with dozens of countries."
