Agree, for me less words on screen is a feature not a bug. At least for the shape of my brain, it stops me from getting lost in the text or skipping up/down the page accidentally. The side/front page turn button redundancy means the act of page turning just fades into reflexiveness and I end up reading faster and retaining more
There are e-readers that put a single word on the screen, this can fit plenty in a decent font size, you'll have to switch pages more often, but I haven't found that to be an issue, the button is very light to press and the page transition (with Crosspoint) is fast.
