Curious, what was the failure mode on the broken kindles?

I have a Kindle Keyboard (k3w) and k4 both going strong (including decent battery life) after a decade of use and abuse by my kids and I.

The jailbreak on kindles that support it (don’t connect your new device to the internet until you have checked) is simple and painless - I prefer koreader to plato but they are both great and an embarrassment to the locked down systems these devices ship with.

Kobo is great but Amazon has better bang for buck (due to subsidy and access to the best eink screens first).
