In part because of this comment, GPB, I decided to check out Notebook before I got too settled in to OneNote. WOW. Exactly what I was looking for. What a thing of beauty, in so many senses.
I'm keeping my collaborative work stuff on Evernote, and moving all my personal/family stuff over to Notebook. By reducing the number of notebooks on EN to the bare minimum, I can live with the non-grid view. Besides, I don't want to force our team to another system, at least for now.
But for anyone who works more in visual spaces and is more at home in an intuitive mode, Notebook is a home run. Again: WOW.
