No, I haven't used Scrivener, though I read about it with interest. My assessment (from a distance) would be that both Scrivener and MyInfo can perform two important functions -- note-taking and writing drafts -- but that they have different strengths. Scrivener, I gather, is an excellent writing tool that is also pretty good at gathering and organizing information. MyInfo is surprisingly efficient as a simple word-processor (I've used it in that way from time to time) but really shines as a note-taker.
