The world has been scrutinizing newly-appointed Microsoft CEO Satya Nadella's every move. Early indicators signal a welcome departure from his predecessor Steve Ballmer.

Satya Nadella and Steve Ballmer

In Ballmer's 12-year tenure, Microsoft was profitable but outpaced by competitors. While Microsoft's market capitalization slid from $288.9 billion in 2002 to $226.8 billion in 2013, Apple's shot from $6.8 billion to $456 billion during the same period. While Apple and Google launched disruptive technology like the Android, iPhone and iPad, Microsoft was often slow to capitalize on advancements in mobile music, smartphones, and tablets (though the success of Xbox and Kinect were surely victories). For example, despite fantastic reviews of the Windows Phone 8.1, it may be hitting the market to late — iPhone and Android have already gobbled up 97 percent of the worldwide smartphone market.
