I find it interesting, now that the App Store is an established brand and venue, that Apple could add this "enable installation from anywhere" option. If this had been present at the time the App Store had launched, developers would have tried to sell their apps from their own websites, and used grunkly stuff in the system they shouldn't have been touching. Can you imagine Adobe releasing Acrobat Reader for iPhone that used some kind of Adobe installer and updater? But now that everyone knows to go to the App Store by default, and developers are climbing over each other to get stuff in there and meet Apple's requirements, I think it's a safer move to allow third-party stuff. The people who are serious and want to make money or spread their brand will still be targeting the App Store, and the people doing things on the margins get the choice put whatever they want on their phone.
