> where the app asks permissions after it is installed (e.g. internet access, local file system access) for each thing it wants to do

iOS does the same for the permissions it supports (access to photo library, contacts, GPS/location, twitter accounts, etc etc), but a lot of things are always allowed (such as internet access). Facebook also lets you deny specific permissions to apps on their platform. I've always wondered why Android and browser extensions don't let you line-veto deny permissions.

There's a tradeoff here - apps become harder to write because you know have to deal with a larger set of possible configurations.

App authors also might shut off the app in less you give it all the permissions, which will cause users to just say yes every time.

Which, of course, is ironic given that every update to the facebook app on Android asks for more and more permissions, to the point where it can do almost anything now.
