Is Microsoft shifting its focus again, or losing it?

"We, as a company, are optimistic about what technology can do for us." Those were among the first words said by Microsoft's CEO, Satya Nadella, as he took the stage at the company's Build 2016 keynote. If that statement seems overly broad, it's not the fault of Nadella's speechwriter. The company's keynote was a reminder that Microsoft has its hands on many tech projects, and sees bright days ahead. But much of that future may not involve things you might find on an average store shelf.
