I did a lot of research on the topic when I started my university studies in microengineering. At the start of uni, there's a lot of money and time being spent by students to set up the "best note taking environment" to ensure their success, usually resulting in expensive iPad Pros with Apple Pencils or the Windows Surface equivilent. In the end I chose a simple piece of software for my 2012 Thinkpad: OneNote. Why? Equation support. There are so many problems with it, but after trialing it against paper and pen, I never looked back, just for the ability to quickly flip back to last-year's lecture/exercices on-the-go. We each have our own journey and find our preferred solution, but here are a few reasons why I chose OneNote over the plethora of other available solutions. It's free. I wouldn't mind paying for something, but this gives you peace of mind that it will stay yours without restrictions, like Google Docs/Sheets/etc. Secondly, it's fast. It's an optimized Windows app that starts in the blink of an eye and uses few system resources. It's visually simple, doens't distract you and has nice smooth animations, it's easier to read/write formatted text with equations than muck around with Markdown/LaTeX. Instant sync, in fact, real-time like Google Docs between devices. The equation support is great once you learn it, it's almost as good as LaTeX. It has pretty decent spell check (although I wish I could set a preferred writing language and not have it deduce from my active keyboard). Good organisation into books, sections and pages. Students get unlimited storage with OneDrive, so no problem there, and trust me, it will be a while until you exhaust your free storage with note taking. Paste images/screen captures, tables. I've never used the pen mode because I don't have any device with a stylus, but I prefer text anyway for it's searchability and typing speed. It takes a little while to really understand the formatting engine, but once you get a feel for the markdown-like underlying invisible structure, it makes it easier to format and move things around. You create your own style and organisation that you can understand and navigate quickly. It's one of the things keeping me on Windows, sadly. Encryption is absolutely not important for me for lecture note-taking, anything remotly important I'll stick in 1password or on a locally encrypted drive. The day I want to migrate, I'll export it as PDF and archive it in the fairly unlikely event I will want to refer back to something. Over time I've learnt that what's in your head is more important than having a perfectly organised personal wiki of knowledge. I would reconsider it for the long-term, but it's fantastic to use something that feels polished and backed by a large company, like GMail vs settings up your own VPS/email software and client. I'm not a fan of big-tech endorsed products, but I can't seem to keep myself away from this one.
