What's the problem with evernote, I was not aware it is dying. Been happily using it for years, and it does everything I need. Admittedly I just need it for usually text only storage of notes and todo stuff.

After reading this article I tested OneNote (on windows desktop). It seems to have lots of features but seemed difficult to use for plain text editing. You could move the text boxes around and paint in the note etc but that was just annoying for my use case.

And the screen capture tool just grabs a portion of the screen? No nice annotation of the image like in skitch? And easy drag and drop of the annotated image into another program like a chat window? Yes you could annotate the image in one note of course but no easy way I could find to then drag the image + annotations to another application.

Maybe I just don't know how to use it but that is just the strength of evernote and skitch, dead simple to use.

And skitch's annotation graphics are way nicer than the pixelated lines of onenote.
