For those that want to export notes into txt or even MS Word docs I recommend cloudhq. This site will sync notes from evernote to another service like dropbox and vice-versa. A fault I find is that cloudhq does not export the notes directly onto the local directory but to other cloud services. You would have to then download the exported notes from that cloud service.
+1 For this. Once you start typing in a black blackground looking at a white background hurts your eyes.
