Pixo also produced a version of the operating system used in Apple Computer's iPod. This seems never to have been formally announced, although the iPod's "About iPod" display include a mention of Pixo, and a Connectix biography of their VP of engineering Mike Neil ([1]) mentions his role as "lead architect on the Pixo OS that is used in ... the Apple iPod".
On June 26, 2003, Sun Microsystems announced its intention to acquire Pixo.
