Seems I gotta try KOReader then, thanks!

Mine is a 2E, the only less-sluggish thing I found I could do was to limit the number of books on it, which seems ridiculous because I have zero PDFs, only epubs & barely using 2.3GB out of 16, and what does it have to do with page turns anyway ?

Ah, it’ll remind me of the times I “hacked” my kindle just to display the cover of The Hitchhiker Guide To The Galaxy :)
