Live-Blogging Apple's Conference Keynote - NYTimes.com Apple is making a keynote presentation on Monday at its Worldwide Developers Conference, held at the Moscone Center in San Francisco. As we reported earlier, the company is expected to introduce upgrades to its mobile operating system, iOS, including a new map service that does not rely on Google for the underlying data. It may also talk about new Mac computers and features for its next Mac operating system, OS X Mountain Lion. I will be live-blogging the event here starting at 1 p.m. Eastern time, with contributions from Nick Bilton, the lead Bits blogger.
