This is a special episode in remembrance of Zain Nadella, the son of Microsoft CEO Satya Nadella and his wife, Anu Nadella, who died Monday at the age of 26. 

Those who knew him are remembering Zain for his wide-ranging taste in music, his bright smile and for his profound impact on his dad's life. Zain suffered from asphyxia in utero and developed cerebral palsy. Satya Nadella wrote candidly about his experience as Zain's dad in his 2017 book, Hit Refresh, and he spoke with me about Zain's influence in an interview that year on stage at the GeekWire Summit.
