Chip-maker Intel should be ashamed of itself for efforts to undermine the $100 laptop initiative.

Intel is selling its own cut-price laptop - the Classmate - below cost to drive him out of markets.

Professor Negroponte, who aims to distribute millions of laptops to kids in developing countries, said Intel had hurt his mission "enormously".

Speaking to the BBC News website earlier this year Professor Negroponte said: "The concept has received a lot of criticism and yet after that criticism they are either copying it or doing things perfectly in line with the concept.

"Yes people laugh at it, then they criticise it, then they copy it."

Both Intel and Professor Negroponte's not for profit organisation, One Laptop per Child (OLPC), have developed a low cost, robust laptop aimed specifically at school children in the developing world.

Intel's Classmate PC runs Microsoft Windows and Linux

There are various differences in both the hardware and software, but Professor Negroponte believes the main problem is that his machine uses a processor designed by Intel's main competitor, AMD.

"Intel and AMD fight viciously," he told CBS. "We're just sort of caught in the middle."

Professor Negroponte says Intel has distributed marketing literature to governments with titles such as "the shortcomings of the One Laptop per Child approach", which outline the supposedly stronger points of the Classmate.
