How many books per year does Bill Gates read? What does he read?

How about other related people (CEO's, tech people)?

A good answer doesn't necessarily have to answer the Gates question
(ideally it would), but you get the basic idea...

This might interest you:

"One student told the story of her trip to Portugal to receive
Microsoft's Road Ahead prize, awarded personally by Bill Gates.
Representatives from each of the winning projects were able to ask
Bill a question. Jaana asked him if he read books outside work, and if
so, to tell about his favorite type of literature. (For readers
panting to know what Bill Gates reads in his free time, the answer is
science fiction.)"

"[Bill Gates] has a photographic memory. He's not a trained
speed-reader but he speed reads. I asked him how many books he read on
his vacation and he said 30. He writes up notes in the margins and
sends them back to the author."
