OP, just curious, when you scan threads about jailbreaking like this one and the hassles of maintaining your jailbreak on a Kindle, what are your main reasons for wanting to jailbreak?

I looked at this issue earlier, and though I jailbreak some of my devices, with Kindle it didn't seem worth it. I like KOReader app for instance, and run it on my Kobo, but with my Kindle PW4, I'm able to do everything I want to do (like install custom fonts, or send articles from Pocket) without needing to jailbreak. And the built-in software is pretty decent.
