17-inch unibody MacBook Pro is unveiled

At Macworld Expo 2009 in San Francisco, Philip Schiller, Apple's senior vice president of marketing, announces a MacBook Pro that features a nonremovable battery designed to last about eight hours between charges. The starting price of the new notebook, which comes with either 4GBs or 8GBs of memory, is $2,799, the same as that of the old 17-inch model. It is set to begin shipping by the end of the month.
