This idea just came up in my head when I was watching WWDC 2005 and the Microsoft 5 year commitment. At the end of the 5 year commitment by Microsoft to make Office for Mac, Microsoft could kill the Mac Business unit. I came up with this from seeing that Microsoft recently killed all but one of the popular apps for Mac (IE, VPC, and WMP). The transition to Intel, a growing features list in OS X, and a higher marketshare of the Mac has produced more competition for Microsoft could give them the incentive to abandon MBU. Also, Gates will leave in 2008/2009, just before the MBU commitment ends in 2010, possibly leaving Steve Balmer at the top, who is much more committed to Windows and anti-iPod not to mention a bit loose in the head which brings up the possibility that he could end the MBU and shift resources to developing Windows. In short, Microsoft might go on the offensive of the Mac vs. PC competition and use its control of Office (a app that would be important to many switchers) to hurt Mac growth and increase usage of Windows. This means that now is a great time to switch to Mac with better performance, reliability and safety along with Office and Boot Camp. This also means that if Microsoft kills MBU and Office for Mac, it will hit the Mac hard (possibly resulting in reverse switch in customers), leaving a window of opportunity for Apple. Apple could have seen what Microsoft was going to do and recognized that window of opportunity which could expain the recent introduction of the Mac vs. PC ads, Boot Camp, and increasing features in iWork to increase switchings and comphensate for an absence of Office for Mac. I just thought of this and I would cringe at the idea of no office for Mac, so please dont flame me!
