I think there's a good point here. Setting aside supported distributions, and package managers... would Evernote be Qt or GTK? Command Line options?
As much as I would like to say otherwise, I think we as Linux users need to accept that we are never going to be a targeted OS for Evernote. Geeknote is solid for Terminal fans, and Nevernote is an option for GUI.
If you want something that's 100% Native, Turtl is an option, and can be self hosted.
