OLPC XO laptop

I have now an OLPC XO laptop thanks to Frits Hoff from the foundation.

The design of this so called $100 laptop for kids from the developing world dates from 2006. I played with it at FOSDEM 2007, while it was still in preview. Since then it has started the minilaptop ‘netbook ‘ revolution. And while it is 3 years old, it still has many innovative concepts which are not yet common¬† in other laptops. Many laudatios have been written, but let me¬† share two features which I still appreciate: When there is enough light (or too much light for other laptops), the screen is very readable with the back-light switched off. This is a big energy saver. And while you are only reading the screen, the operating system (Fedora Linux) powers down most of the laptop components. It’s really impressive to see the power led go on and off while the screen remains powered. Netto result: between 0.3 and 8W is enough for the OLPC, while my other laptop consumes often 40W. The day I forgot my OLPC power supply, I could use another one from a dead Sony walkman with power specs (5.4W) lower than any other reported usable power supplies (see my contributions at the OLPC wiki).

Frits Hoff suggested me two current OLPC issues (mainly in the developed world) to think about: Flash support and speed improvements. (continue reading…)
