Free classes from MIT

Okay, this isn't exactly new news, but it is news to me, and I think this is way too cool.
MIT, and many other top universities are giving away their classes for free, sort of. Here is the news article, and here is the link to MIT's OpenCourseWare.
MIT is offering over 1,800 classes, including some of their most coveted classes online for free. Basically the only thing you don't get is to raise your hand and ask questions and of course, you don't get the college credit's. But the education is free, which is amazing to me.
