I can understand an update to an app for security reasons, but it seems more and more I have to update my computer, phone, and iPad just about every week. Also sometimes the update includes changes I don't want or need. What gives? Is there a source where I can read about updates to decide whether I need them or not? Can I turn off notifications so I am not reminded to update all the time? Personally I think they should put updates into categories and classify them like security, features, extras, etc.
