I watch my classes on my desktop computer and my IPad. I love the 30 second rewind (YouTube doesn't have theis), also the bookmark function.
Some of the classes have quite a few pages to print. So I am keeping them in a 3 ring binder. Make sure you sign up for the 2012 and 2013 BOM classes. They are free and even if you don't make the blocks, you will learn a ton of good stuff.
