I used to be an avid reader but somehow life always gets in the way these days. I don't enjoy longform audio books because I only ever have 20-30 minute snippets of time and you lose the sense of flow jumping in and out in such short bursts. I love that with Headway I can put something on whilst i'm driving somewhere for 20 minutes and get an entire book summary in that time, so I feel like I've both learned and achieved something. The summaries could be a little bit clearer/better at times, but overall, I think the concept and delivery is brilliant and I am using it loads.
