I don't think it'll tank this time. And why should it? Here we are in a major recession, and there is a company turning a profit....A huge profit! And with a solid cash reserve to get it through these tough times.
All the PC people in my office said that Steve is on his death bed. And that Apple has no one to take his place. They saw it on the news. And even though they have never even touched a Mac since OS 6/7, "Why should I care about a dying company?"
WTF does Apple have to do to get through to these people? They will never, ever even consider it.
