Euclid is a new business model in textbook distribution. The company aims to give free tablet PC to students. Students still purchase e-textbooks or digital e-learning contents, just as they would any hardcopy textbooks or CD multimedia contents. This new business model allows every student to own a mobile computer for free and allows publishers to distribute e-textbooks and e-learning material more efficiently. It is good for education because it allows schools to achieve a 1:1 student-to-computer ratio without any additional cost. It is a One-Laptop-Per-Child, except free! www.euclid.com.hk
