My iPad Pro 9.7 is my preferred device to read on. I've also got an older iPad Mini 2 which I used prior to getting the Pro 9.7. I was concerned the Pro would be too big, but it really isn't in my case. I read ebooks in two column landscape mode, and did so on the Mini 2 also. I long ago gave up on those small 6" eInk screens preferring the larger, color, high resolution screens of the iPads.
