SAN FRANCISCO — Apple Inc. is refreshing its iPad lineup in hopes of reclaiming lost ground in the tablet market and slashing the prices of its Mac computers to intensify the pressure on the beleaguered makers of PCs running Microsoft's Windows.
Tuesday's unveiling of Apple's latest products primes the company for a holiday shopping season onslaught aimed at a list of rivals that includes Google Inc., Samsung Electronics, Amazon.com Inc. and Microsoft Corp.
A thinner, lighter and faster-running tablet computer called the iPad Air highlighted the event in San Francisco. Apple Inc. also showed off a souped-up iPad Mini that boasts a faster microprocessor, a high-definition display screen and a higher price than its predecessor.
The iPad upgrades, coming a year after the release of the tablet's previous generation, fell largely in line with analyst expectations.
In a surprise, Apple is introducing slightly revamped MacBook Pros at prices 9 percent to 13 percent below the previous versions. What's more, Apple is giving away its latest Mac operating system — Mavericks — for free, as well as several pieces of software, including programs called iWorks and iLife that provide many of the same tools as Microsoft's Office.
"We are turning the industry on its ear," Apple CEO Tim Cook said of the company's strategy.
Technology analyst Patrick Moorhead predicted the discounted MacBook Pros will force personal computer makers to cut the prices of their machines by at least $100 for the holidays.
And Ovum analyst Jan Dawson thinks Apple's giveaway of the operating system and software programs "is now teaching people to expect both of those things to be free. While this won't disrupt Microsoft's business overnight, it will create further pressure on Microsoft to bring down prices."
