The hits seem to keep coming for Microsoft who has hard time imposing Vista on the market, faces issues with Excel, a flagship product, and lost an important legal battle with the EU Commission over its competitive behavior. While Microsoft's tactics justifiably cause customers to be concerned, I believe the weapon of market dominance ends up being a boomerang for a company because its erodes its relational capital with customers and local communities, drives intense reactions from competitors and regulators and probably leads to some form of complacency and arrogance of its personnel, who may end up believing that whatever they release will end up being bought by a market taken hostage by their employer.
