First of all: Steve, get well soon.
As for Apple (AAPL), it plays on the edge of the law. Maybe lawyers can prove that Steve's health is a private business. Maybe. But for the market it's material information, no doubts about it.
For me, Apple is not an investable company anymore. I still have a small position, as a speculation play. But long term investment is not for me. Accounting irregularities equal sell, what about informational irregularities?
Full disclosure: at the time of publication author had a long position in AAPL. Positions can change any time.
