I use Evernote (paid plan), but it's been my impression that the level of intuitiveness of the UX has steadily declined, to the point where I have no idea what to click to make it do what I want.
Like Yahoo, some companies are very challenged when it comes to building intuitive UI/UX. It's too bad the market focuses on financial performance and market share rather than more fundamental aspects of competence.
Couple of years ago I was OneNote user (on Windows). Then I decided to switch to Mac, and moved all my notes to Evernote. I was happy at first, but then Evernote started declining in quality. Microsoft introduced OneNote on the web, on the phone, on the Mac, and last month I switched back. It's free, and it is, at least for me, superior user experience.
I switched from OneNote to Evernote when I got a Surface. The only things I like Evernote better for are its simple file format (OneNote will be harder to get my data out of if I leave) and its Clearly web clipper. Outside of that, OneNote is just better put together and much more intuitive.
Being able to draw with a pen is awesome, and the killer feature that makes it work is "Insert Space." You can pick a point and push everything below it down, like you would when making edits in a word processor. All the layout and diagram flexibility of handwritten notes, but without the usual limit that you run out of space or have to work in the margins if you want to go back and add anything in the middle.
