Definitely prefer a real book, of course a ton of convenience to be gained by the various ebook readers. One thing I’ll say I have a very hard preference for though is at least an e-ink screen when reading on a digital device. Spend enough time on backlit screens, way nicer when I can’t have a physical book to have e-ink and regular lighting.
Bookstack looks really cool, considering it for a project at work but I don’t like how you can’t have pages outside of books. We’re looking to put together a general knowledge base that could span many different types of equipment and manufactures. For that reason I’m leaning towards wiki.js due to the search and tag browsing, but basically planning on doing the same installing those same 3 to check them out.
