As JKOnTheRun notes, The OLPC (One Laptop Per Child) operating system is now downloadable and fits on a USB thumb drive. You can download it, dubbed "Sugar on a Stick" at the Sugar Labs site.

There are a lot of Windows users out there who use high-profile open source applications such as Mozilla's Firefox browser, but fewer of them tend to reach for the many free, open source applications that they could easily be benefitting from.
