Yeah... have to disagree there... I don't think they do nearly the QA/QC that their pricing model would have you believe. They'd have to just flat charge $100 for every time you submit a new app version for it to be that way, or closer to it and that would require much smaller cut of revenue to make sense. Meaning less overall money to apple, but higher quality over quanity.

For a practical example, see what LinkedIn did a few years back... I trust nobody, and am largely disinclined to install any/most applications.
