Being sucked in to MS Office suite by SharePoint (Score 1)

Would love to move to the OpenOffice platform. Microsoft has simply ceased to have any innovative thinking within its Office suite. This is even more painful after experiencing the absolute joy of Firefox for the past few years. But we're looking at implementing Sharepoint at our company. My initial reaction to the product itself is quite positive. There are many features that will help us. But, it as a bit of a Trojan Horse (I know, not the best analogy). In order to maximize Sharepoint's functionality, we need to upgrade to the 2003 Office suite. Arrrrrrrgh. MS is cleverly further embedding a stagnant product into our company (Office), while sucking millions of dollars from us in upgrade fees.
