After demonstrating Mavericks OS X from the San Francisco stage, Craig Federighi, vice president of software engineering at Apple, spoke Tuesday's golden word: "Free." Federighi did not mean a "free update" or "free trial." For the first time, Apple is offering its newest operating system for Mac, 100 percent free of charge, a product that historically would cost nearly $200. To boot, Mac owners with any version of a Mac operating system released in 2006 or later will be able to upgrade directly to Mavericks in a single step. "Today we're revolutionizing pricing," Federighi said. A phrase that rang true again when Apple revealed its new iLife and iWork suites will be free with any new iOS or Mac purchase. In addition to the freebies, Apple is also offering its new MacBook Pro line at a lower starting price than previous generations. The new 13-inch MacBook Pro starts at $1,299 and the 15-inch starts at $1,999.
