It's official: Microsoft (NASDAQ:MSFT) has named Satya Nadella as its new CEO, ending its search for new leadership. A 22-year Microsoft veteran, Nadella has led the company's important cloud and enterprise segment to riches. That gives him crucial experience in managing Microsoft's most profitable business. Last quarter, the commercial segment drove nearly 2.5 times as much operating income as the devices and consumer segment.

On the flip side, some investors may be disappointed that Microsoft didn't tap an external candidate who may have pursued dramatic strategic shifts. There had been speculation that some candidates would have been interested in killing Bing or selling off the Xbox business to focus on Microsoft's core strengths. Additionally, Bill Gates will devote more time to Microsoft's strategic direction, which is a curse and a blessing at the same time.
