"With the iPad making up over 80 percent of the tablet market and millions of people worldwide using Office, that could mean big bucks for the tech giant based in Redmond, Wash.," Hickey wrote in his report. "In addition to an iPad-ready version, a new edition of Office is expected for OS X Lion sometime next year." Currently, Apple has a few Office-like productivity apps of its own, with its iWork suite (Pages, Numbers and Keynote) on the Mac, iPhone/iPod Touch and iPad. If Microsoft were to challenge iWork on the iPad (and maybe even iPhone) with Office, apps for Word, Excel and PowerPoint could go head-to-head with Apple's own productivity apps.
