Have you ever tried [org-mode][1]? It's an emacs major mode for taking notes, making to-do lists, building websites, having an agenda, etc... It's quite powerful since it's basically a markup language. It can be exported to multiple formats (including latex) and supports writing code and even executing it inside the same file with [babel][2].

Everything's saved as a plain text file so you can sync them across different devices with Dropbox, Drive or even git (which I use).

I've tried emacs a long time ago but could never get it to stick. With everybody advising me to switch to org-mode I might have to give it another try.
