Forstall is in charge of iOS, the operating system that powers the iPhone and iPad. This makes him one of the most important people at Apple. He was dubbed “CEO-in-waiting” by Adam Lashinsky, who wrote the excellent book, “Inside Apple.”
Forstall has more stock coming: 150,000 shares in 2013, 100,000 in 2014, and another 150,000 in 2016 if he sticks around.
Still, it’s curious to see someone so high up sell almost all of his stock.
