Thanks Russell. You raised a good point about the Libre.
I loved the contrast and very fast page turn in libre alongside the fact there was no whole screen turning to black when page turn like E-Ink. My major concern was the charging I guess. Since I never got anywhere close to 20 hr and I'm used to reading a lot, often 4-6 works in weekdays and over 10 in weekend. So I needed to charge like every other day or so which was bit irritating specially since I didn't have a safe place where to put the reader to charge at night

. Didn't want a kid or other family member dropping it or whatever. Also the page turning option wasn't as great which maybe the same with other readers.
How many hours do you go by in JBL?
But thanks for reminding me of the option. Also the price is great.
