Apple's new iOS 6 isn't limited to the iPhone 5, of course, but the mobile operating system's new features will certainly entice people to buy the company's new handset. What's new? Well, Siri is smarter. She now fields sports queries, including questions about scores and standings. You also can use Siri to launch apps, get movie recommendations and make dinner reservations -- "Find an Indian restaurant for two around 9 p.m." -- and post Facebook updates.
