I do use OneNote in a similar way, but the problem with OneNote is that I am constantly tempted to start "decorating" my notes, using all those fonts, graphical tags (why not to mark this line with a nice star or question mark icon?) etc. Huge distraction.

Is there anything similar for Windows?

Nice. This is an abacus, actually.

that's an abacus!

Now than I have an Android phone, I really don't care. I always have something to read, watch or listen.
