I just can't believe the whining that goes on here; some people really need to grow up. Apple is a big, wonderful company. Of course they stumble from time to time; why on earth would that come as a surprise to anybody?
At the end of the day, their products are usually better than the competition's, the stock has done very well, and they keep coming out with products that people want to own. As for the stock: if you've owned it even just for one year you are still in positive territory and you've had a TON of opportunities to take a profit along the way.
So the SDK is going to be another few weeks. If this is really going to make a huge difference in your life, you have bigger problems than the lack of apps on your iPhone.
And for the record, I am an Apple user and a stockholder. I've gone through all the ups and downs of the products and the stock. While I admit I've been frustrated from time to time I understand that no company, even Apple, is perfect. We need to be much more realistic and a little bit more patient.
