That's interesting, and makes me want to read more about Apple and Steve. Cook seems to still be a big unknown in a lot of ways. My biggest question about the future of Apple is whether they'll be the first with the next revolutionary device. The iPod, iPhone, and iPad didn't have any fundamentally new technology, but instead put together existing technology in a way that redefined how we used and thought of the whole class of devices. Nobody made a music player that was simple to use and just worked before the iPod. Nobody made a truly finger-friendly touch-screen device before the iPhone. Nobody made a tablet that was really practical until the iPad. I don't own or use any of either of them regularly, but I can appreciate the effect they've had on the market.

There will be more revolutionary devices in the future. Will they be created in Cook's Apple? If they are created, is Cook the man to bring the right device to the market at the right time? That's what'll be interesting to see.
