I find the comments today quite weird.
1) Stock market is time invested. Had I purchased Apple Stock when I had the chance I would have made significant return on investment even at today's current price.
2) Many complaints of Jobs in the past seem to not be the case as much now. A) He is showing much more gratitude to those working at Apple. B) He has been sharing the stage more with others who work at apple. I can remember years ago complaining about "What will happen to Apple after Jobs?" or "Jobs is an egotistical jerk." So, Jobs has been the in the process over the last couple of years or reproducing himself.
3) If I'm not mistaken, Jobs doesn't do everything at Apple. So, someone else has to be designing, writing code, testing, coming up with ideas, etc. Apple is not just one man.
4) Timing of new products is important. And nearing or at the bottom of an economic slowdown may not be the best idea to launch a new product that people may not buy, or if they do, will not be in numbers that would make the product a "success." Further, having new products launched just before or at the beginning of major shopping seasons would seem to make more sense.
5) How often has Apple been complained about for showing a new whatever in January, set a target date, missed it, and then ticked everyone off because of the delay? Apple controlling their product launch cycles makes way more sense.
6) Apple has cancelled appearances before, so this is nothing new.
I could be wrong on all this, and I think mostly the comments on AppleInsider are good. But this thread seems way out in left field. Even if his health may be the reason, there seem to be far more reasons that make Apples move a smart move regardless of Jobs health.
Funny how it is in America that we always like to knock down the top dog.
