That's odd. I've had and evaluated the XO-1 using Jepsen's displays and found them to be of low quality for even that timeframe. Even basic things like the resolution were terrible for that time. There's good reasons why they (both OLPC and PixelQi) were unsuccessful. OLPC was a disaster and in my opinion just a way to transfer money from the education budgets of developing countries and UN funding into the pockets of people who enjoyed hanging out in swanky incredibly costly offices at 1 Cambridge Way with guys like Nicholas Negroponte, Joi Ito and Jeffrey Epstein instead of actually achieving real progress.
