Why?
Dedicated ebook reader = cheap, charge lasts months, can read in sunlight
Phone = have one anyway, always with you, keep it charged, But small screen can't read in sunlight
Tablet = already own one or buy $50 cheap slow 7" one. But poor battery, can't read in sunlight
Dedicated ebook tablet = expensive, don't already own one, poor battery, don't always carry it, can't read in sunlight. Why am I buying this?
