Erasing and dragging are enough to make my reMarkable worth it, but for random brainstorming I need real notebooks that I actually keep on hand. Never been sure why, something about having to physically locate my writing somewhere is huge for me.
I can quickly turn the RocketBook sketches into pdfs and send them to the reMarkable for further processing...but, I love the flexibility between the two, and honestly, the reMarkable fits in the pocket off my RocketBook...so it's not difficult to carry both.
The more that I use reMarkable, the more I fall in love with it, but, I wish I could find a way to make my own templates.
I'm taking a college cryptography class, and I started by maintaining notes with LaTeX in Markdown. It didn't help much. The moment I started using a Rocketbook was when I would get things. I've reused my book about 5 times now in conjunction with work and other classes. I'm on my sixth cycle and love it!
* I can scribble group meeting notes and share them in Slack by just scanning from my phone and they come out great—including drawings
* I can scan my notes quickly as PDFs and keep them for years to come
* Some classes allow me to upload and refer to my notes during exams
* I don't waste any paper
As for wasting paper, even in my furious note taking days in college, it didn't amount to that much paper. I don't think the stack after graduating reached a foot high. You'll waste orders of magnitude more paper throwing away junk mail, food packages, etc. Besides, paper recycles easily. Plastic rocketbook pages, nope.
Additionally, when I was in my undergrad I still went through a lot of paper. I have bad habits when I scribble notes or solve math problems. But with this, it's the only notebook I carry.
I don't have separate notebooks for work, subjects, home, etc.
