Compared to say the complexity of a current model mobile phone or tablet, which doesn't require a wall transformer (well Android in any event), why does a rather simple (in comparison) ebook reader?

Are you saying you have an Android mobile phone that you plug directly to an AC outlet to charge? Or are you talking about needing a stepdown transformer to convert the local mains voltage to a voltage the charger will handle? Looking at the wall wart you posted a picture of, you will notice that it will handle 100V-240V 50/60Hz AC input and outputs 5V, 1.0A which will charge most USB connected devices.
