@colinwalker I agree with @benedwards. When my iPad was attached to a keyboard, I hardly ever used it due to the heavier look and feel. I've freed it and started using it exclusively for reading. I read on the Kindle and my wife reads PDFs on it. Much more use that way.
But my experience is different because it's an iPad Mini. YMMW with and iPad Air 2 due to the size.
@nitinkhanna I have been using my iPad Pro 1 Gen since it came out as my main device. Yes, for most part I had Apple keyboard cover attached to it. With that, I realized I have hardly been using Apple pencil with it. So I removed the keyoard cover about 6 months ago. Since then I have been using the iPad even more. As a result though, it has been seldom, I even open the lid of my brand new MacBook I purchased in December last year.
