1st Kindle DX: Screen cracked, not sure why. Maybe thermal stress? Amazon replaced for free.
2nd Kindle DX: Stopped booting, no physical damage.
Kindle: Rolled on it after falling asleep, screen cracked.
Kindle Oasis: Dropped directly on its face, screen cracked. This weird anti-bezel obsession means there is nothing to protect the screen. But you need a bezel to hold onto, so not having a bezel makes the device worse in most ways.
The Kobo that I have has large plastic bezels, so it is easy to hold, lightweight, less likely to be dropped, and when dropped, unlikely to suffer direct impact to the glass surface.
