"Developers! Developers! Developers!" That chant might trigger nightmares of a rather sweaty Ballmer, but what was true almost a decade ago is now even more critical for Microsoft's success. Yes, success, not just survival. There is little doubt Microsoft could live on for a few more years on life support should Windows 10 flop, but if the next operating system is to become the success that Windows 8 was not, it needs to have more apps. Not just any app, clones or fakes, but the kind of apps that make iOS and Android users go nuts. And to get those apps, Microsoft will obviously need developers, developers, developers.
