I have OneNote ... cool tool, but it's heavyweight (IMO) and not terribly portable.
I even use vim quite bit 
I have used the free One Note app on my iPad, my iPhone and my Galaxy Tab - everything syncs via One Drive cloud sync. I have One Note on my Daw (not a powerhouse by any means). Pretty much just keep it on the Galaxy Tablet and my Daw now. I disable my wifi when working on my daw, but enable it otherwise which allows One Note to sync. Nice to have access to daw project notes etc, on my tablet.
MS OneNote, or a different note app called One Note? Either way my phone is dumb as I'm not iInclined. By portability I mean between applications (not to be confused with apps).
MS OneNote (and office) on my DAW. Freebie apps of same are available on android and iOS. Stripped versions but fully functional. I do all entries etc on my DAW in the full soft, access everything on my tablet or other devices.
As for portability between applications, I think OneNote is the ultimate integrator - I put Excel spreadsheets, word documents, tables, all kinds of pictures, html, screenshots etc into OneNote. I don't do anything/much the other way, but can't imagine it'd be difficult to go from, eg, OneNote into word or excel.
(Sorry about the space - definitely talking about the Microsoft program and its associated apps)
