This was innovation in its own right. Steve annoyed me with some of his views, often excluding capabilities like blu-ray, RAM upgrades in the iPhone/iPad, etc., but I always admired his tenacity. Tim's doing fine, and I think he's starting to get better at certain things, but Steve will always be missed.
This pretty much sums it up. SJ made decisions that often were infuriating and seemed at the time to abandon the loyal Apple core customers but he was almost always right.
Tim Cook doesn't seem to have nearly the ego that SJ had. He won't seek credit for being a touch negotiator or decision maker because he doesn't seek attention. But he has made tough decisions and IMHO is doing an excellent job. Innovation does not follow a schedule and Wall Street is a bunch useless hot air.
