And if you listen at 1.5x speed, does that just burn your 15h faster or can you fit in more time?

It's an interesting idea, but I think the only way I'd use it is a "try before you buy" and go out to Libro to make the purchase. At least that's the only way I could realistically see using 15h/month.

That's half an hour a day. Most people are not going to rip through that. Sure you and I would, but most people that's probably adequate.

It's what. A book, maybe book and a half per month? Like cool that it's an option but it's not really something makes a difference for me.
