I am an Evernote Pro user since early days of Evernote. I am using both Mac OS and Linux and it's a shame that Evernote is not providing a client for LINUX. I am sure there is a business case.
I'll migrate to 100% LINUX next year and that will be the moment in time, when I'll have to say goodbye to Evernote if nothing happens. A pity, the company's management seems to try to learn it the hard way, how to loose loyal and paying customers and loosing them for good.
