Going with your logic, it's correct to say that it's a bad e-reader, because it's not an e-reader but a Kindle.

What you all guys mean by Kindle? I have one for like a decade and I don’t get it. It’s not a strong brand of itself like iPhone (which is also smartphone).
All I can tell about it is that it’s a mediocre reader and that’s it. I don't upgrade it to any other reader because it just works, so I’m going to keep it till it won’t.
Yes, you can dislike the Kindle, but to say it's a bad e-reader is like saying a bicycle is a bad car.
