Yeah. I personally have nothing against paper books - except they are heavy and waste space. And when you think about it, you're holding what amounts to a 5mb data file (with multiple immutable passive display screens) and it's about twice the physical volume of a 500gb hard drive and doesn't mass much less. Wildly inefficient! A micro-SD card the size of your fingernail could store a thousand times as much.
