MiBook takes a different approach from other e-book readers.  In contrast to some that have tried to duplicate the look and feel of the printed page, the designers and marketers of MiBook are fully aware that it is an electronic device.  It eschews the E ink technology found in many recent e-book readers that attempt to mimic the appearance of a black and white printed page, instead opting  for a standard LCD display that can display colors and refresh quickly, but also drains energy faster.  "Books" pre-formatted  for the device are not the usual software files you download and transfer, but memory cards you plug in.  However, the memory slot accepts standard sd cards, so instead of purchasing one of the preformatted books on card, you can load your own card with text and multimedia files.   One big advantage MiBook has in in price. It is significantly less expensive than other e-book readers.
