Have Kindle. Used twice to make the giver happy. She's now threatening to buy me a Kobo. Ereader is better than my phone, but not enough better to justify lugging it around. And if im home there's my computers or physical paper books. If i was living out of a backpack or a locker, an eReader would be great.
Pirate site https://libgen.rs has more ebooks than anyone could read in a hundred lifetimes. No DRM, direct download, can read epub on my phone or computers. If i like the book, i then buy the physical.
