Hugh Pickens writes "For years Google has been pitching migrations from Microsoft Office to Google Docs, arguing that Docs makes Office 2003 and 2007 better because users can store Microsoft Office documents in Google's cloud and share them in their original format. Now eWeek reports that Alex Payne, director of Microsoft's online product management team, says that moving files created with Office to Google Docs results in the loss of data fidelity, including the loss of such data components as charts, styles, watermarks, fonts, tracked changes, and SmartArt. 'They are claiming that an organization can use both seamlessly,' Payne writes. 'This just isn't the case.' Meanwhile, Google defended its original 'Docs makes Office better' in a statement, noting that it has made a lot of improvements to the web editors in Docs with its recent refresh, and promising that functionality will only get better as Google integrates the DocVerse assets into Docs. 'It says a lot about Microsoft's approach to customer lock-in that the company touts its proprietary document formats, which only Microsoft software can render with true fidelity, as the reason to avoid using other products,' says a Google spokesperson."
