I'm on a mac and I get probably 2 updates a week on average. I always install them, I never postpone them. I don't know if that's due to a bug or what but that is what's happening. I do agree it's a bit much and can be annoying when you're trying to work and you have to wait for it to download and install. Even if it takes 30 seconds, it takes you out of your work flow and can be a bit frustrating. Chrome used to have this problem and they solved it a long time ago by doing updates automatically in the background. I know that's not necessarily trivial thing to accomplish but maybe that would be something to look into for Evernote. As a software developer myself I recognize the need to keep your product update to date but that has to be balanced with overall user experience.
