I agree. This limitation is just plain stupid. I don't want YOU to care about my security, I want to have an app I can use in all my devices. I want to be able to work offline! I don't use evernote with any data that will need security! SO just open that option for the user who want to use it, and put a big disclaimer before. So the ones who want security, use internal device memory, and the ones who doesn't need it, can use the sd.
