The latest posts about broken screens have been very discouraging but someone correctly mentioned that most people who receive a working device probably won't post about it. So here's mine, it works as expected and I'm already in love even though I received it just yesterday.
The display is crisp and easy on the eyes. I hope that they will keep some models with no backlight even after the release of S4. I have a kindle for night reading so no backlight is a feature for me, not a bug.
I find the buttons comfortable to use regardless of which hand I'm holding it with. The device itself is super super light without a case which is perfect for my chronic wrist pain.
I got the magnetic flip case, feels sturdy but a bit heavy compared to the device. I like that it's easy to take it off when reading at home.
One last thing to mention is that I've noticed thin horizontal lines appear on the screen if I leave it on for longer but disappear when I refresh the page. Hopefully this is normal and not a screen issue.
