Taking a page from its friend Linspire's hymnal, Canonical, the brains behind Ubuntu, has started offering its flock proprietary Parallels widgetry so it can run Linux and Windows on the same desktop without rebooting. It is Canonical's first dalliance with a proprietary package, but evidently not its last. The Parallels stuff can be found in Canonical's Ubuntu Partner Repository, where Canonical intends to push both proprietary and open source third-party software, and will be available to Ubuntu users as a drop-down menu on the operating system.
