OLPC's Founding CTO Mary Lou Jepsen

OLPC's XO has been much in the headlines recently. If you want to find out it all from someone who knows, there's a good interview on Groklaw with the ex-CTO, Mary Lou Jepsen. And no punches pulled, either:


Q: The world is now very aware of the spoiler role that apparently Intel tried to play. Can you though talk to us about the differences technically between the Classmate and the XO?

Mary Lou Jepsen: Where to start: Classmate is more expensive, consumes 10 times the power, has 1/3 the wifi range, and can't be used outside. Also, the Classmate doesn't use neighboring laptops to extend the reach of the internet via hopping (mesh-networking) like the XO does. So not only is the XO cheaper than the Classmate, the XO requires less infrastructre expenditure for electricity and for internet access. In Peru we can run off of solar during the day and handcrank at night for an additional $25 or so per student – this is one-time expense – the solar panel and the crank will last 10 or perhaps 20 years. Just try running electricity cables up and down the Peruvian Andes for that cost while making sure it's environmentally clean energy. The Classmate isn't as durable as the XO, and its screen is about 30% smaller, the batteries are the type that can explode and only last 1-2 years and can't be removed by the user and harm the environment. The batteries are expensive to replace: $30-40 per replacement. The XO batteries last for 5 years and cost less than $10 to replace. Finally, the XO is the greenest laptop ever made, the Classmate isn't – this matters a great deal when one proposes to put millions of them in the developing world.

Fearful Symmetry

I've noted before that Microsoft is in difficulty over the ultra-mobile machines like the Asus EEE PC; now it seems that the other half of the Wintel duopoly is also in trouble because of the new triple-P (price, performance and power) demands these systems make:

Two days before Intel CEO Paul Otellini would unveil the Classmate 2 or the Intel-powered XO at the CES, Intel announced that they are quitting the OLPC board.

Intel claims that they are quitting because of Nicholas Negroponte wanting them to stop the promotion of the Classmate/Eee to education in third world countries, but I think that the real reason is that Intel does not have a good enough processor for the OLPC project to use as an alternative to the AMD Geode LX-700.

Intel has not been able to develop a processor to match the price, power consumption and performance requirements of the OLPC project.

Bye-bye Wintel, hello Linmd?
