God's Debris is an interesting example... I first read it on a Palm as part of a research study into the usability of so-called "e-books".
I then printed it out for other people to read.
Going back to it, if I can't find my printed copy (it's easier to lose a print-out than a book) I'll have a go at reading it on my computer screen, but it's hard to snuggle in bed with a 17" LCD...
But if I had a book-sized e-book (the Palm was too small,) I'd probably use it.
