OLPC (One Laptop Per Child) operating system and desktop environment (called Sugar) a test run. They have a live CD available on their site, and I used VirtualBox to run it. You can click on the image below to see the rest of my snapshots. Interestingly, the “window manager” is not similar to anything I’ve seen on any platform. They do have gnome running on the one I tested, so you can switch to that at anytime. I’m assuming that will be part of the actual OLPC. Nonetheless, despite being a weird and new environment, I found it pleasant. And it’s all free and open source software.
