I had enjoyed and even paid for Evernote for several years, until their "restructuring" and they dropped the export of everything but "Evernote Database"... I think they have since restored an export to HTML, but that always was the biggest problem for me... I want to be able to export (and backup) my notes in TXT or MD, not just HTML or their proprietary format.

No idea if they've since added in more reasonable export features, but it was a dealbreaker for me (a big plain-text fan).
