One of the problems with the smaller screens is less real estate for a keyboard. One of the really cool things about the later models of iPads and iPhones is the thumb print reader and how many apps are allowing you to use that instead to typing in your password each time. For the apps that support it, it really works well. Just wish that Apple supported it with regards to signing into iCloud!
Apple's design philosophy has long be simplicity. Thus they don't really support the super customization, be all things to all people model. They provide you a preferred solution and that's the end of the matter. Sometimes I like it, sometimes I don't. I hate that they removed audiobooks from playlists, but their solution for going from one audiobook to the next in cars is carplay. If your car doesn't support carplay, well then you need to buy a new car! That's the Apple philosophy.
