I have already seen in community threads, and in other forums that there is no Evernote linux client.
On this matter, two points of view:
General: Already the number of users who use or want to use Evernote in Linux natively is great. At least, it's my impression in the Arch and Ubuntu forums, as in the social networks on Linux. Many comparisons in articles, podcasts, etc., of note programs and organizers are made against Evernote.
Individual: I am a 100% Linux user, for 2 years. And Evernote is an app paradigm within the field. And it is imprencindible to have Evernote in Linux, to be able to work offline with notes, notes and documents attached to my academic and professional work (I am a computer consultant in companies, and administrator of networks in a University).
Thank you for your attention.
