Well I was just thinking I would take some notes on the class, but not kill myself trying to get everything, and if there was something important that I missed, I might be able to go back and find what it was. But I was just planning on taking notes, recording the lecture, and saving the lecture just to go back and maybe refresh my memory. Depending on how I am on taking notes, I might not even need this, but the only thing it would really hurt is my hard drive space.
I've been looking for a bit and these two have caught my eye, I just can't decide if I would want to pay $85 more for 64mb more.
