I jailbroke it, launched KOReader, and it's like I have a new e-reader. The amount of customizability gets kind of in the way, but once it's set up I don't really think about it from one month to the next. I also didn't feel the need to upgrade my original install either.
The hardware is great, but the software is pretty lacking. Apparently a lot of the tools out there are from folks in similar situation: had the hardware, but the software to drive it was lacking.
Most software has compromises.
KOReader seems to have functionality in one place in one reader app that other e-reader apps don't.
