So much this. A few years ago, I could open Evernote and instantly start capturing all sorts of stream of consciousness ideas, solutions, etc. Even with a few thousand notes.
Now, I start it, and by the time I've updated and synced and can actually do something, I've already lost the train of thought. Oh, and a bunch of new notifications have arrived to distract me. Even without an update, it's painfully slow.
And I can't leave it sitting open because of the memory leak issue I've experienced (bringing my 32GB system to its knees until I killed the Windows process).
