I've checked it out before and it does look like a top contender. I have 2 major outstanding questions/issues.

First, how to migrate? I have tens of thousands of notes in many folders. Not something I'm willing to do manually.

Second, does it allow for mixed notes of text and pdf or images of written notes?

The barrier to entry has kept me out a bit because it looks like a big job, but would be interested to hear if someone else had pulled it off.
