On iOS, I can trust that pretty much everyone in my family won't download something silly that then creates a security hole in their devices. Not sure how you could guarantee that if you could load code post-review. What would be the point of the review, then? Wouldn't the App Store be littered with trojan horses in waiting?

It already is littered with outright scams, apps pretending to be other apps etc.
