SAN FRANCISCO -- Apple Inc. (>> Apple Inc.) on Monday unveiled new laptop and desktop computers, as well as the latest version of its desktop operating system.
At the company's Worldwide Developers Conference, the company announced a new line of Macbook Air laptop computers that it promised would have "all day battery life" and faster Wi-Fi capabilities. Phil Schiller, Apple's marketing chief, said the new laptops would begin shipping to customers immediately.
Mr. Schiller also previewed a new version of the Mac Pro desktop computer, promising faster speeds and a size about one-eighth that of previous models. The computer, which will be assembled in the U.S., will be released later this year, he said, without giving specifics.
"Can't innovate anymore my a--," Mr. Schiller said, seeming to refer to recent criticism Apple has faced over its pace of new releases.
Earlier in the keynote address, Craig Federighi, who runs Apple's Mac and mobile software groups, unveiled new Mac operating system software, dubbed "Mavericks" in reference to a surfing spot in Northern California. It includes new ways to handle multiple windows and screens, as well as new power-optimization features.
Mr. Federighi also announced a password retrieval application called iCloud Keychain that will work across Apple products to help users login to websites.
Mr. Federighi said the software would be available in the fall.
Mr. Federighi also announced Apple's iBooks application would be available on Mac computers for the first time. The company has 1.8 million books available for download in its digital bookstore, he said.
"Now your books are available on whatever device you choose to read them on," said Mr. Federighi.
Apple Chief Executive Tim Cook earlier announced the company's app store now has 900,000 apps available and has paid $10 billion to app developers since the app store was opened more than five years ago, about half of that in the past year alone. Google Inc.'s (>> Google Inc) Play store has about 975,000 apps.
