Apple's former Senior VP of Mac OS Software Bertrand Serlet has joined the board of directors at Parallels, the virtualization software company in a non-executive role. Serlet, who did stints involving both science and programming at Xerox PARC as well as Steve Jobs' former company NeXT, left Apple last year to focus "less on products and more on science." His role at Parallels will be to help supply additional vision and direction for both its flagship product and its server-management tools.
