If they get the price of this down to $200, and textbook companies would make searchable textbooks for it, this would be great in a high school or at a college.
Students could search their textbook, we could download textbooks at the circulation counter (I am a librarian), and students wouldn't have to lug around 30 pounds of books in their backpacks. Teachers could also send assignments to the students through the wireless connection. You wouldn't need storage rooms for all of the textbooks, and we'd save shipping costs and all the labor for processing of textbooks.
I can't wait to get my hands on one of these!
