> Most Microsoft purchases at a large organization are rational only because of how much the company has already sunk into Microsoft. Microsoft's strategy had never been centered on their software succeeding on its intrinsic merits.

Microsoft has lots of crappy software, and I personally find MS Office rather irritating, but I'd still argue that it's the best office suite currently available. Like yes, it has lots of bugs and weird misfeatures, but all its competitors are either buggier or only have less than a tenth of the features that MS Office does.
