Ok my experiences with reading in bright direct sunlight is excellent and in dimmer light with its reflective lcd screen I can usually tilt the screen in the direction of the light source and have a decent reading experience (i.e at night in bed with a night stand lamp for lighting) . If let's say I was going camping or read at night out doors on the beach, a battery/ rechargeable clip on reading light work well and with the jetbook or Libre's reflective screen you could get by with a less powerful light.
