We tried using Windows 10 for real work and... oh, the horror
While working with Windows 10, I found it hard to believe that this is a product three weeks from release. The back-of-the-envelope direction for Windows is the right one, and there are promising things happening all over Windows. But the experience suggests a wildly chaotic development process. Microsoft seems to have veered from trusting a dictator to abolishing the figure of authority completely. Separate teams just seem to have done their own thing, with management having faith it would all come together in time for the release date. (...) In fact, even now I'm wondering if the Windows 10 Insider Preview is not some elaborate piece of theatre, a kind of front. That perhaps a stable version of Windows 10 that nobody outside Redmond has ever seen is quietly maturing away, without the zany UX experiments (and bugs) of the public preview version.
