Any real benefits of jailbreaking a Kindle? I mean I know the “You free yourself from amazon!” elevator pitch, but what exactly does that mean?

I can already upload pretty much anything I want to it with Calibre. Can I add support for other ebook formats? Cooler utilities on my Scribe? Alternative ebook stores (yes I know where I am)? A user interface that isn’t absolute garbage?

Because it’s not “just a fancy interface”?

It makes the entire process from purchase to playing completely painless, on top of a large community of people, guides, achievements, etc. I think I’d maybe improve my performance by like…a fraction of a frame per second. Good trade off.

And as others have mentioned, Lutris does a good job if you don’t want steam.
