In two days, IBM will have finished preparations to transition all of its employees away from Microsoft's Office suite to their own version of the OpenOffice.org suite, Lotus Symphony. By Monday, every IBM computer will have Symphony installed, and the company will begin creating and sharing only open format documents. The move marks the most significant shift away from Microsoft's de facto standard office suite and proprietary document format by a single company, and—if well documented and supported—could help many other businesses do the same.
