I have owned two Kobo Wifi readers—the first one had its screen cracked while I was backpacking up in the mountains. That was in 2014. I could have upgraded, but I was perfectly happy with that model and picked up a used one. It’s still perfectly adequate to this day.
I use it to read public domain books—like Don Quixote or The Odyssey. I recently read The Adventures of Telemachus; now I’ve started reading Fear and Loathing. I have tried reading modern literature, but the book quality is usually just too poor. I prefer to check those books out from the library anyway.
At any rate, I am pretty amazed that this nine-year-old device still functions so well. I am happy that I don’t need some book-loading software. It plugs in like a USB drive and I copy ePubs onto it. Nothing to it.
Anyway, as a long-time customer, just wanted to say that I think you’re on the right track!
