KOReader is amazing, I had an old Kobo Clara HD that I almost had given up on, and after installing KOReader I use it almost daily as I read a lot of documents on it. You can ssh it, so you can easily scp kobo to send/receive documents, like epubs, pdf or retrieving highlights you've made on the kobo. Plus, it is installed on top of the normal kobo operating system via NickelMenu, so it's not really messing up with anything.
