The Importance of Separation Between Dropbox and Evernote

Evernote really is more of like internet stuff you know pattern like I do crafts so like knitting patterns would go in there. Dropbox is all the papers that I would ever really need to be able to reference again later and that are specific to projects. Evernote is sort of like a working space as opposed to a saving space for me can you know does that make sense?
