Absolutely right about Kindle. I did not elaborate that point. My daughter, when she was 5-ish, used to think I do not read because I'm on a Kindle. So, after going fully digital I went back to physical books about 5 years back. Now, I mix about 1 physical for every 4 kindle books. At 11-year, she do gets it now and have her own Kindle with one -- you can read as many books as you want.
