I have already cited two main definitions of "magical" above. As I just pointed out, it depends on who "your understanding" refers to. It's not either complete understanding or totally mystified; there are many stages in between. Of course most of us understand the need to recharge it, avoid dropping it, etc. I don't think even Christian fundamentalists believe iphones work through angel power :-)

Maybe it's because I'm a Londoner - that I moved to Nice.
