iPad is unreadable outdoors in daytime. glass surface acting as a mirror and display not being transflective. also it is way overpowered to display text. so it's battery is depleted after 12 hours instead of a few months. i'd love a transflective ipad with image-persistence on powerdown. notionink seems to offer this i think?
