Rob wrote with a link to a Computer Business Review online article, which reports that Microsoft chairman Bill Gates and Apple chief Steve Jobs will make a joint appearance at a future technologies conference in Carlsbad, California. The event is expected to last a little more than an hour, and the two computer industry magnates are expected to reflect on their pasts - while theorizing on the future. "[WSJ Tech columnist] Walt Mossberg, a co-producer of the conference who will interview the execs on-stage along with colleague Kara Swisher, said they simply invited Gates and Jobs to do the interview ... [Mossberg] declined to give any color about the questions he and Swisher are preparing, or any additional information. Most likely, Gates and Jobs will use the occasion to do some friendly sparring on their polar-opposite philosophies on personal computing. Jobs may bang on about the benefits of a software-hardware approach, while Gates may rattle off the joys of partnering with hardware partners."
