Kindle is amazing. It is like a global library with the widest selection available to you with one click. Especially with Kindle Unlimited.

Together with Kindle + Audible, I am finishing on avg 2 books a week. Once done, I go through the highlights, brainstorm on them and add my notes to those highlights right on Kindle. Good one for knowledge retention. This, you can't do with physical books. Or you can do, but with enormously higher effort.
