Yes I agree and we're all different and interesting what you say. The lighted cover for me works really well, even though the newer led front lighting is a huge advance, I use it often and wouldn't get anywhere near the use out of the KKs, without it. It's kind of more like a torch on a real paperback, only better and still very adequate. I've never had a problem with my jailbroken KK (did this one too; SS, fonts etc.) and Kindle Collections plugin for Calibre. I see the Kobos are much better with it and most likely if I do ever buy a new one, it will be a Kobo now. But the old and brand new KK, are all I could wish for, right now.
Since I'm new here and probably can't edit my posts yet, there were a few typos in the original post: publishing was
not my main profession and I left it a few years ago, I've always loved books and set up an imprint for cross media work, once.
