I'm going to reduce my 5,000 notes in Evernote and move a couple of thousand to OneNote. I already pay for Office, so the "look and feel" is already familiar to me.
However, if EN were to stick with the Legacy edition and do moderate upgrades I would likely stay (but I think EN has said that they will not be adding or updating the Legacy version.
Sadly, after many years of using EN, I don't see how I will keep going with it. The new versions are slow and lack features I have used for years. I'm sorry to see a great company go down with their long term users.
