Zotero is designed for collecting citations and associated pdf's. I can go to ArXiv.org or a journal website and grab all the info on a paper and a PDF copy with one click. It's not a general purpose tool, but similar to endnote or bibdesk for managing papers. It's for people who do extensive research, e.g. faculty and grad students. Evernote is really not designed for that.
