> Anyone have experience of using an iPad mini for this. Is the form factor do-able or really too small?
I contemplated doing that, but went with an iPad Pro instead (11’’, second hand). Even 11’’ felt a bit small and I got a 13’’ eventually. Besides screen size, the Apple Pencil 2 is miles better.
> I like that I could read lying down with one hand, which I can’t achieve with a full-sized iPad.
Yes, for reading a Mini would be much better. More Kindle-like. The 11’’ Pro is still manageable with one hand (but without a case), but it’s not comfortable.
