How many ereaders did you own/use over the years?

[Odyssee]

Looking back, my history of e-reader usage is quite extensive. I wonder how yours looks like.

2008: Irex Iliad
2011: BeBook Club
2012: Sony PRS-T1
2013: Kobo Aura
2015: Kobo Glo HD
2016: Kobo Aura One
2019: Kobo Forma
2022: Kobo Sage

The Sony was the first useful device. Because of the inbuilt light I switched to the Kobo Aura. I loved my Aura One because of the larger 7.8"screen and the Forma, which I rate as the best one I had so far, because of the page buttons. I wish I hadn't bought the Sage.

2011: Kindle Basic (silver)
2013: Kindle Basic (black)
2014 (end): Kindle Basic with touch
2016: Kindle Voyage and Kindle Oasis 1
2017 (end): Kindle Oasis 2
2019: Kindle Oasis 3, Nook Glowlight 7.8" and Kobo Libra H2O
2021 (end): Kobo Sage and Kobo Libra 2

The buttons are a must-have for me. I've only had one buttonless reader, the Kindle Basic with touch, but I couldn't get used to it.

The last two, Sage and Libra 2, are what I'm using now. I still have the Kindle Oasis 3, but all the others have been sold or given away.

Editing to add comments.

I was thrilled with my first Kindle in 2009, it basically gave reading back to me. I pretty much hated the little basic Kindle with the skinny page turn buttons. It was awkward and clicky, and by far my least favorite.

My first Paperwhite was a bit mottled, but the front light improved my reading experience again. The next generation of the Paperwhite I still have, and sometimes play the active content games on it. It has a bright pixel right in the middle of the screen, but that wasn't there when it was new.

The Kobo was ok screen wise, but the least stable of any e-reader I've had. It locked up frequently. The Oasis has been a disappointment, dismal battery life, weird behavior, and I don't like page turn buttons. The 2019 Paperwhite is a great device, and the newest larger screen Paperwhite seems very solid, but I've only had it a short time.

- Kobo Touch
- Kobo Glo
- Kobo Aura H2O
- Kobo Libra 2

I've generally been happy with all of them.

My Libra 2 is my first one. Well, at least my first dedicated reader. I've also read a lot of books on my iPad.

2012 : Kobo Touch
2021 : Kobo Clara HD

Both are in use

I loved the iRex's a lot, but I'm pretty happy nowdays with Kobo and Koreader.

I've always kept a spare when buying a new one.
I hated the Aura 6", but a young niece loved it for years and refused my newer, better ones; now she prefers paper books.
The Clara was the first perfect 6" I owned, but my old eyes need bigger real estate, and a cousin who can't read paper books anymore loves it. She doesn't want a bigger one though her eyes are much worse than mine and she has few lines per page.

I'm fuzzy on the years, but:

1. Kindle Keyboard (2011)
2. Kindle Paperwhite (2013)
3. Kobo Aura (2017) - a refurb that was a great introduction to Kobo for me
4. Kobo Clara HD (2019)
5. Kobo Libra H2O (2020)

I'm always chasing the next shiny e-reader -- even now I want to switch to the Kobo Libra 2, just holding out in case they release something else this year. Also, I love the buttons on my Libra H2O. I don't think I'll go back to a buttonless e-reader anytime soon.

[pdurrant]

An interesting question. I think I'd count my PDAs and Phones (i.e. pre-Ink reading devices) too. I'll have to come back to this when I have time to delve into my archives.
