But Office as a business unit is one of the cores, add in LinkedIn as another business unit - and they're building out the entire business systems ecosystem, end to end. Hiring (LinkedIn), HR (Office + LinkedIn), office productivity (Office), communications (Skype + Sharepoint, WP?), training (Lynda), infrastructure (Azure). Guessing next step will be another attempt at advertising/marketing platform. EDIT: forgot about Dynamics for that last one.
