I've used emacs solely for orgmode over the last year and I'm not sure I'd recommend it whole-heartedly. Orgmode is great, but the emacs learning curve is steep and unforgiving. It still feels as if I'm faking my way through an ancient language whenever I fumble through keyboard "shortcuts".
That said, it's incredibly powerful. Wouldn't continue to torture myself if it wasn't. I like the plain text files, the authoring experience (the document feels alive somehow), and I've never been more organized. I just wish it existed outside emacs!
