Apple beats Microsoft at its own Open XML game

Computerworld - Apple Inc.'s release of iWork '08 this week is "embarrassing," an analyst said today, not for its maker, but for rival Microsoft Corp.

Tuesday, Apple rolled out a refreshed iWork that added a spreadsheet, dubbed Numbers, to the earlier mix of a word processor/page layout Pages and presentation maker Keynote. But it was iWork's ability to handle the Open XML file format -- the new native format for Microsoft's own Office 2007 application suite -- that Michael Gartenberg of JupiterResearch LLC talked about.

"This was the ultimate insult to injury," Gartenberg said. "Not only has Microsoft not delivered the ability to read and write Open XML in its Mac Office, but at the end of the day, Apple was the one who delivered."

Gartenberg referred to Microsoft's problems developing Office 2008 for Mac, which the company announced last week would be delayed until mid-January. Among the roadblocks, said Microsoft's Macintosh Business Unit (MBU), is the shift to Open XML as Office 2008's native file format. The company has also been slow in releasing conversion tools that let earlier editions of its Mac suite work with Office 2007's Open XML documents.

"This is embarrassing for MBU," Gartenberg said. "It has said that the shift to Intel has caused [its] problems, and changes in development tools, and the file format, too. But every other major vendor has pretty much managed to get their apps over to Intel [on the Mac]. Microsoft is one of the oldest Mac developers out there, so it's not like it doesn't have experience [on the platform]."

IWork '08 applications can open the OpenXML formats churned out by their Office 2007 counterparts -- Pages with Word, Numbers with Excel, Keynote with PowerPoint -- but cannot save in those formats. Currently, Office 2004 and Office v. X users can both open Word and PowerPoint Open XML files and save in those formats using beta converters MBU has issued. No such converter has been released that handles Excel 2007's Open XML files, however.

Ironically, one of those who praised iWork's handling of the Microsoft file format was a program manager for Office 2007. "[iWork '08] reads the Office Open XML files with very high fidelity," said Brian Jones on his company blog.

At the same time, Jones defended his fellow developers at Microsoft in MBU. "The Mac Office folks have a ton of stuff they are working on for the next version, so it's not surprising that you aren't seeing full Open XML support until they reach that point," Jones said in response to a question asking how Microsoft lost the race to Apple's iWork.
