Moren's final point seems to be that an excess of 99 cent apps is pushing the really talented developers out of business (because they can't make back what they put into the software by selling it for 99 cents), but there's still something wrong there. If someone can sell 100,000 copies of an app for a buck apiece (walking away with $70,000 after Apple's cut), why are the talented developers leaving? Surely you can make a quality app for less than $70,000, right?
We're obviously still closer to the beginning of how the App Store will eventually shape up rather than the end. It sure seems like developers who create worthwhile apps would find a way to pay for them, but if they can't, then yes, it might be worth another look at the pricing setup from Apple end.
