PS, I have a few clues for further arguments, but I am not sure how to express them so that they do not feel like weak arguments.
Firstly, there would be the fact that you should own the books you buy, and thus be able to give them to whom you want, as you would with an actual paper book.
Then there would be this :

And finally, there would be the fact that it could be one more positive aspect for selling Kobo e-readers since people are sometime (often?) asking themselves such questions before they switch from paper to e-ink. At least, this is why a few friends of mine bought a Kindle instead of a Kobo, although the Kobo has some interesting features the Kindle hasn't got.
