Highlighted parts of the Kindle:

Back arrow: This can be accomplished by holding your fingers in between pages, sure. But the back arrow can keep going back as you run out of fingers.

Search: Why point this out? Books can't do this. It shouldn't count against the ereader, because it provides extra functionality. To be equivalent to the book, just ignore it: and now it doesn't matter where it is.

Menu: Why point this out? It leads to functionality that books don't have.

Go to: Yep, you can flip pages, potentially finding a spot faster. But wait: Go to can go directly to a chapter/page. You'd at least have to flip back to a ToC, if you have one, or flip through lots of pages.

X-Ray: Again, why highlight this? It's something books don't have.

Bookmarks: Do you know how many times bookmarks have fallen out of my books? When I take a bookmark out while reading, should I place it elsewhere in the book, or maybe on my nightstand? I've had to search for lost bookmarks countless times this way. But wait! With my Kindle, I don't even need to access the bookmarks in general, because it remembers where I left off.

Back/forward: I can turn pages one-handed. With a book, you have to carefully grasp a page to turn it (make sure you don't grab 2 or 3!); or you can try to flip with your thumb (make sure you don't flip 10 or 20!) With my Voyage, I can use buttons, tap the screen, or swipe on the screen. I'd much rather tap a thumb (my usual method) than flip pages.

Quick preview (whatever that "swipe up" bottom bit is called): For flipping, I cede to books. If my goal is to flip quickly through pages, my Kindle is inferior to books.

Basically, this image seems to criticize ereaders for having extra functionality. That, to me, is bizarre. There are a multitude of things I think my Voyage does better than books, and a couple of things I think books do better than my Voyage.
