@Tedpeer :No, iPad can't replace textbook.

I guess you aren't working in a scientific field where all the papers, textbooks are "large", A4 size, i.e from an iPad point of view.
It doesn't seem to change a lot of thing and people think you only have to zoom in, zoom now, back and forth. But when the paper in question requires all your attention, it's very distracting.

And I don't write about the intrinsic problems of the tablet per se where you can't shuffle so quickly between pages, going from one-two pages before, and coming back... Yeah, you can do that by putting bookmark each time on each page you are currently reading than erasing them etc... but it's not so good.
