well technically that's not legal either,
your example is akin to converting your purchased music from CD to I-gizmo or vice versa. I don't have an issue with it but corporate lawyers see the world differently.
they'll argue that you don'' buy ( i.e. own) an e-book ever- you just own a licence to view it on a particular gadget in a particular format, until such time as they change their coprorate minds ( like in the 1984 kindle fiasco)
