******Shortly after 9 a.m. California time, Apple Inc. Chief Executive Steve Jobs took the stage at Macworld, the biggest conference of the year for the maker of the Macintosh computer and the iPod.******Expectations for announcements this year are for an uber-thin and uber-small notebook Mac and perhaps an online video rental service.******And, of course, perhaps there will be the usual, “Oh, and one more thing…” That last phrase is a vintage Jobs tactic for saving “the best” for last at Macworld. But nothing is likely to come close to last year’s Macworld, when Jobs unveiled the much-anticipated iPhone.******Spotted this year at Macworld milling about before the festivities began: Google Inc. co-founder Sergey Brin, Google CEO Eric Schmidt and San Francisco Mayor Gavin Newsom.******During his keynote, Jobs announced a wireless back-up device called Time Capsule and software updates to the iPhone, among them including local location mapping technology.
