I would assume a powerful feature of Evernote (from a GTD perspective) would be to send yourself your emails that require actions (something easy to do with Evernote). I tried to do this with my free version of Evernote (I have thus far only used the web app - not desktop or mobile) and it says I can only send 5 emails or I can choose to upgrade to the premium version. My question is that for those of you who frequently email your actionable emails to Evernote: Do you all use the premium version of the software?
