In this video, Zack — who wouldn't mind testing technology when he works as an adult — looks at a new tablet technology that may change the way we use books -- textbooks, that is -- in class. The tablet is called the Kno, and it's currently being developed just outside the city in Silicon Valley. This could change how we work and read in high school or college. The tablet is expected to cost less than $1,000. While that is a lot of money, a tablet like this could be an amazing tool that is fun to use.
