I really like this. I only have one computer, and it spend the whole weekend on the office. When I'm home I want to learn something, with my iphone. The problem is, the actual MOOC alternatives don't have mobile solutions. Now Udacity allows you to download the videos. But this is not natural and I have to put on my dropbox, open a video at once, and sometimes they have 6 second videos. Now I can learn when I'm on the bus and on my couch. Thank's Khan Academy!
