John Loiacono, Sun's executive vice president of software, describes features of the company's upcoming Solaris 10 operating system at The Tech Museum of Innovation in San Jose, Calif.

Chief Executive Scott McNealy holds a prototype of Sun's "Niagara" processor, due to arrive in 2006. The chip consumes 56 watts of power and has eight processing engines, or cores, each able to run four simultaneous instruction sequences, or threads.

President Jonathan Schwartz pledges to build a better open-source community around Solaris than the one Linux possesses today.
