The problem with a simple switch is that many users are unable to grasp the implications of the permissions that they are granting, so they are better of without that choice. We are talking about a device that holds a large amount of personal information, the implications of bad security are far greater than being simply being p0wned. A locked down, less flexible but more secure device is a better choice for them.

On the plus side, there is no need for antivirus software in devices running iOS, something that I saw advertised prominently the last time I was in Akihabara. Certainly, the rules to get a iOS developer license could be relaxed in such a way to demand less than $100 for it and make room for hoobists, but locked down nature of the devices and the efforts made to get accountability from the developers are a service to Apple's customers.

For most people phones -of any kind- are appliances. For them the lack of freedom to run any arbitrary code is a good feature, and are well served by Apple's model.

Yeah, it is not like the vulnerabilities used by jailbreak tools could ever be also used by malware or anything.
