But seriously, hopefully Microsoft will benefit from him and become a bit more popular amongst nerds.
Why do you hope for that? Microsoft pretends to reinvent itself regularly, but one thing remains constant through the decades: Their goal has unswervingly been lock-in from top to bottom, while trying to nickel and dime you the whole way.
For nerds, this means locking you into their programming languages (e.g., VB or C#), or if not that, at least lock you into their APIs (so that you're as good as locked in, even if you're using C or C++). It means abandonment of entire domains that no longer suit them (look up how woefully out-of-date and ignored the C part of their C/C++ compiler is).
It means locking you into their platforms, whether that be the operating system (Windows) or the browser (Internet Explorer).
It means high prices (have you seen the prices on Windows Server and/or Microsoft Azure lately?), which is not-at-all nerd-friendly. It means guaranteed stagnation in those domains where they achieve dominance. It means product churn for the sake of profits. It means ignoring customers and forcing bad implementations on them (*cough*Metro*cough*) and then taking forever to admit it was a mistake and fix it (when is Windows 9 due out? Next year sometime?).
Just because some new-boss-same-as-the-old-boss is singing some unicorns-and-rainbows song doesn't mean the core of Microsoft is going to change. They're still after the same things they've always been after: Lock-in so severe that the pain of escape ensures most people remain slaves, and profits, profits, profits.
