Throwing an iPad in and out of your bag to "just check" something is going to be a different kettle of fish to getting out a notebook, opening it up, waiting for HD to whir up, loading Safari/whatever, blah blah.
The iPad will be the sort of device you can leave lying around, in your bag, etc, and then just refer to at will. I can read it easily in bed without scalding my legs or hearing a fan going at a gazillion RPM, I can read it easily at a coffee shop without looking like an idiot, I can draw on it and take full sized notes wherever I go.
It's not just for replicating notebook stuff; it's for new stuff too.
