if you’re using Zotero check out Papership which is a pretty good iPad client. I haven’t run into a missing feature yet. Also would recommend, if you want paid hosting, pay for a Zotero account with extra storage (run an academic group at George Mason University, aka the good guys). Don’t give money to Mendeley which is owned by Elsevier (definitely the bad guys).
