The use of tablets for eLearning delivery will continue to grow in popularity. Another good article on the topic is „A Little About Mobile Learning and How to Administer It“ at http://interactyx.com/social-learning-blog/mobile-learning-how-to-administer-it/

This one is a little older, but still relevant „Are We Wired for Mobile Learning?“ at http://interactyx.com/social-learning-blog/are-we-wired-for-mobile-learning/

Hope this helps!
