Follow the money, always
Last 12 months numbers, roughly
- PC Office, O365, and Dynamics - $50bn and growing 20% pa
- Cloud, server, enterprise - $50bn and growing 30% pa
- Windows, Xbox, Hardware - $55bn and growing 2% pa
So Windows is part of the slowest growing division, which overall is around a third of the business. Where does corporate investment go ? Not in the biggest products, but in the fastest growing - and Windows is a long way off being the biggest anyway. Plus a dollar on O365 is more sought after than a dollar on Windows standalone install, for that lovely lovely subscription renewal.
The business purpose of Windows was to provide a foundation for the real money sales of Office. That is no longer true. Office and Cloud can be sold to any OS user. Why waste money on Windows developers when you can leverage Linux developers who aren't employees and don't qualify for health benefits or a pension.
