I have nothing to add to the discussion of Steve Jobs. Will come back? Won't he come back? I only wish Steve and his family the best.
We, as investors and participants in the tech industry, must not read more into this than there is. The simple fact is, the technology industry is only beginning to enter a downturn. PC sales "barely grew" last year and are likely to be stagnant to negative in 2009, at least here in the United States. Google today announced it is shuttering a collection of the services it offers, as well as the laying off of 100 recruiters, a clear signal of tightening by the company. Online ad sales growth is slowing. And Steve Jobs may die, at least there's a strong chance he won't come back to the company.
All these events happening in close proximity will seem to be more significant than each individual event might be. Yet, it is still just a series of events that should not make investors run for the doors. Keep your heads, people, even if the worst happens.
