Who says hacking can't be used for good. A prime example would be in the case of Glenn who is an electrical engineer, who hacked Amazon's eReader, Kindle, and modified it in such a way that made it easier for his little sister to use, who happens to be suffering from cerebral palsy. For those unfamiliar with the condition, cerebral palsy is generally found in young children that affects both physical and mental development, sometimes leading to physical deformities where their arms/legs cannot be stretched out fully.
