You know, while Apple's rejections seemed to be arbitrary at times, I was surprised that my reaction to reading this was that the vast majority of these rules are pretty sensible. A lot of them come down to "your app must not crash or be full of bugs, it must do what it says it does, and it cannot be malicious." For all the hoopla, I expected this list would read like a crazy list of charges handed down by a kangaroo court.
The thing on here which I really strongly disagree with is the ban on making apps that replicate functionality shipped with the phone. If users want an alternate mail client that supports IMAP IDLE for example, it should be up to the user to download that.
