I used to read real, physical books. Prior to 2018, I would buy books on Amazon, but then in 2019 I’ve switched to borrowing from my local library. This move helped with the checkbooks.
In 2020 (and especially post-Covid), I’ve moved to reading on my iPad. I’ve taking up using Apple Books as my primary reader. It’s not the best when it comes to search or real-time syncs, but it does the job for now and it’s interoperable across my Apple devices. (Let me know if you have better ideas or have better setups for your reading materials — would love hear how you currently read).
Apple Books also helps me store eBooks as well as PDFs. I tend to read a lot of PDFs from reports to white-papers etc.
