There's been a lot of talk about the OLPC's cute little mesh networking laptop at Linux.conf.au this week. The foundation is taking its low-cost, robust laptop the XO to underprivileged kids around the world, but it's also funding its work by selling XO laptops to the public. The cool news from the LCA conference was that a local OLPC group is setting up in Australia to help get computers to kids across Australia.
