IGG Software today quietly changed the name of its flagship application, iWork, to iBiz. Rumors have been circulating through both the Mac Web and mainstream press about a possible Apple productivity suite–named iWork–to be introduced at Macworld Expo next week. It is not known whether IGG was forced to change the name of its software by Apple, or whether it simply believes the speculation and wants to differentiate its software in advance. IGG’s Ian Gillespie offered a simple statement on the matter. “We feel that the new name better reflects the direction in which we see our product going, towards business management and not just time-billing,” Gillespie told MacMinute. “We feel that customers will really like the features we plan to add to iBiz and we believe that the name change transition will be smooth.” Gillespie would not comment further when pressed on his company’s relationship with Apple.
