Pens are an addicting technology. Top 5 list of various pens. https://www.penaddict.com/top-5-pens/ I also buy a cool pencil case (http://www.jetpens.com/Kokuyo-Pencil-Cases/ct/2929)
My only difference is when I was in graduate student I used OneNote with 2003 Tablet PC (Hand writing with the pen) and a external microphone. The was the single greatest tool ever created for a student. The audio was synced with your hand written notes or typed notes. I then had the college purchase a license for every student at my University I worked at OneNote and take a 1 hour class with me and a had microphones available at the Book Store. No one ever used the microphone. I got the highest review marks from students for all our Freshmen prep classes and a ton of interaction and people stopping at my office to get help but they all dropped it for one reason or another. If only computers built in a classroom position microphone in the lid of a laptop.
I also found that A5 grid paper on Amazon for a little cheaper[1]. But I'm curious how well the binding holds up. Because if it holds well it'd be a great switch for me.

The next slide after the 43 folders is "sync to paper", that's the bit I recall
I don't think I'm doing a good job of explaining this, I'll see if I can find an example of this online and link it.
Edit: I did a quick google search and found an example that's similar to what I'm doing. This works well for me: http://lifehacker.com/mark-page-line-edges-to-organize-your-...
More ephemeral things like todo lists, I only scan if I have a reason to want to keept it.
I've tried for very long to find a good electronic solution. Up to and including writing my own wiki with various extensions customised to my diting style, and hunting around for every note taking app under the sun.
The problem, I find, is that nothing beats the flexibility of being able to take out multiple sheets of paper and move them around, annotate them, put them back in. It creates a flexibility in workflow no tool I've tried have managed to match.
The physical presence of the paper also makes it much easier to avoid forgetting a page exists.
I'm not happy with it, but I keep coming back to it after each desperate attempt at making something else work better.
