Apple CEO Steve Jobs used a Dell PC at yesterday’s launch event for the Windows version of iTunes at the Moscone West auditorium in San Francisco. He used the system to demo features of iTunes and the iTunes Music Store, which look identical to their Mac counterparts. “I’d like to do something I’ve never done before,” said Jobs. “I’d like to do a demo on a PC.” The San Francisco Chronicle snapped the picture at right. This isn’t news per se, but it’s something you’ll probably never see again.
