I'm in a similar position. I've been using evernote for a while , and have a lot of notes in there but I find my usage tapering off recently.

Thing is, I'm not sure what to replace it with. There's lots of apps that try to tackle one piece of the puzzle each, but I really liked having on "bucket" to put almost everything into in a relatively unstructured way. I've even been thinking about building my own replacement, with the workflow tweaks and slimmed-down feature set I actually want/use.
