I used to love my old 6-inch ebook readers. Now when I look at them I don't understand how that was even possible. Such small context windows. I agree 8-inch is the best size.
I still like the Forma, and I actually bought a second one recently to give me peace of mind. The Sage is a nice device, but the battery percentage ticking down with every page turn reminds me too much of the finality of all being.
Even tough it does last longer with selecting a different governor.
