Agreed. Developers are generally intelligent people but unfortunately many users are not. Sandboxing is for those people and it does its job well. I do think however that there is a case for allowing a vendor-level sandbox so that apps made by the same vendor could share data amongst themselves. This would facilitate free-trial to paid app upgrades. In any case, give it time. Apple tends to start off with a solid base and build from there (rather than throwing everything onto the wall to see what sticks).
