A few things. I already pay for Office 365 every year and Evernote isn’t cheap on top of that. The Evernote app is really slow and clunky. I trust Microsoft with the security of my data more than Evernote and I see that only becoming more true as Evernote seems to be declining in popularity. My main use case is to save stuff down in a massive archive for reference in the future and don’t use it much for active project work at the moment, so it just needs to be stable and searchable.
