My judgment is skewed by having a Surface Book, which is 13.5" (3:2), which makes reading PDFs very comfortable in almost all the cases (exception being only the badly edited PDFs with extremely small fonts). I am very surprised though, that there are essentially no large tablets on the market, as I think 12.* is the minimum for comfortable reading, and I assume there is plenty of people using tablets for reading. I understand that cramming a Windows-capable machine in 13.5 inches and 700gr is reserved to high end machines, but I wonder why they don't do that with ARM CPUs (I'm aware of the Chuwi, but it's 1.1 kg, and 700 is barely the limit for reading for hours).
