Mine do, too. They still have covers.
I signed up for Kindle Unlimited last month. My grandson is an avid reader. As am I. Yes, I copped out. I've read a couple dozen books on my tablet since my layoff.
I have a Kindle fire I take in the field with me. I can have a dozen books downloaded into it for the space of one. But, admittedly, I miss the smell, the feel, the texture of the paper, leaving nose prints to mark my place when I fall asleep...and if I ever go off the road or get caught by weather, I can't cook over a Kindle Fire....

Where the difference is really apparent, I have books back to the 1700s, and the feel and smell of those volumes is entirely different from the ones from the first half of the 20th century, and different yet from latter day paperbacks or hardcovers.
With my eyes changing, though, I like the scalability and back light of the screen.
