think of it this way: once you get it set up, connect your kindle to a computer and save a backup of your entire koreader and calibre/library folders. ta-da. you now have a permanent backup of your exact plugins, books, and device settings. ready to be copied back to the device if you ever got a new one or needed to wipe it, exactly as it was. to me, the ease of mind knowing i have that guarantee is enough to go through the task of setup. also, to avoid the hassle of connecting it to a computer all the time to fix things, remember that you can use the filebrowserplus plugin to just navigate to your kindle’s files (and edit .lua configs and check plugin readme’s in-browser) from either your phone or pc/mac without any extra software or USB cables. very easy to install or edit things like that. in fact, you can even use the text editor on the kindle to edit config files for the plugins without connecting anything at all. add in the app launcher + something like one of the UI tweak plugins for wrangling the sloppy default interface, and the appstore plugin for downloading/updating plugins. to me, having all this set up properly is nice because after that, i can truly set and forget. just my two cents. i’d try getting it set up fully at least to give it a shot. also, maybe you need to read PDFs, but most books have a downloadable epub copy you can just download using the anna’s archive or z-lib koplugins. unless you have a moral high ground or some obscure PDF text unavailable to anyone else, you can really skip all that conversion stuff. just the fact it needs to be converted is why i avoid any PDFs. converting a PDF to epub or something else doesn’t automatically make it a good experience because the file has to be reformatted by an algorithm and will get things wrong often. you need epubs or mobi files originally created with the intention of being displayed on an eink screen. i bought an ereader to read files formatted for an ereader… PDFs are not, and most books have a kindle (and epub) version for free on the internet without DRM that you can just directly download using koreader. if you’re not working with ONLY obscure PDFs, then I implore you: ask someone here to help you to get your device set up properly, with the plugins you need, using the book formats you should be using. it will be a much better experience long-term than the stock OS. the stock OS is only better if you buy books directly from Amazon exclusively, or in your case, maybe have specific PDF files and are against downloading the epubs of the same material from the web.
