zmei92 Judging by the reviews and personal experience there is nothing worse for your old man than 9.3.5. All lag, each launch any application takes a long time, sometimes it seems specially made EPL timer when running applications in 1-2 seconds. It is very much on how the application is started, if you click on the icon to launch and nothing happens. Applications often fall. Generally everything is not working as you'd expect, especially in comparison with quality android / windows tablet. Repeatedly was the desire to send a plate to the wall, but the wall is a pity. I advise you to read more testimonials, so I had no effect on your preferences, but positive feedback on 9.3.5 you will hardly find. Although I do not know anything about your seventh version, still very pleased with 8.4.1. (From 9.3.5 to 6.1.3, and rolled through the air onovil to 8.4.1, thanks to the guys and decided to answer above problem.)
About the reading room, I do not know whether there be of ios, but fbreader has all the features that you have described in your request.
