I used to carry my kindle Paperwhite in my lunch bag, reading on breaks at lunch. Upgraded to a fold 7 this week and have been using that instead, it's beautiful and I love it for daily reading and pretty much everything else I can throw at it. The Kindle app makes looking for new titles (unlimited has so many LitRPG) so much easier than on reader or PC. It's truly changed how I do reading on the go.

Having said that at home I still prefer my kindle, not because of the screen, the size, the physical heft, soft leather case, extreme battery life, no those are all good reasons but physically not much different than my phone. No I prefer to use my kindle because I don't get text messages, reminders about ongoing sales, emails, video streaming recommendations, none of that. I just get my book.
