IBM is buying the strategic consulting skills it could not grow internally. I worked for IBM for 20 years, and every time they would launch a project to develop the kind of intellectual property needed for strategic consulting, the funding was pulled right around the time the proof-of-concept phase was completed. Most of IBM's Global Services revenues are from very-low-margin outsourcing, installation, and programming services. IBM wants the kind of stratgic consulting - like Accenture and EDS have (EDS also bought theirs, but have done a good job integrating it). IBM is generally poor at integrating acquisitions, so this PwC deal should be a boon to its consulting competitors.
