This is one of the most promising crowd-funded projects I've seen in a while. The concept is a rugged e-ink based tablet, which is able to charge fully in 5 hours of sunlight. The e-ink will keep power usage low, extending runtime to an awesome 20 hours between charges. This thing is loaded with features and is almost ready for production, they just need some pre-orders to get them there. With a backer price of $249, this could be a huge hit for those who love the outdoors. Check it out at the link below:
