One Laptop Per Child, the effort to put technology in the hands of third-world kids, has lost its number two guy Walter Bender, who was president, software and content until last month when he was shifted to head of deployment although not many of OLPC's novel Linux-based XO machines have been getting deployed. Bender, credited with building OLPC, has now reportedly gone off to develop XO's icon-based Sugar GU interface - meant to be an intuitive educational tool - and port it to other species of Linux besides the Red Hat Fedora operating system XO uses.
