I don't think they will get into "delivery business". Most likely they will use their own delivery for last mile in the high density areas, but will not make it available as service to competition and will keep it as competitive advantage. I, for one, is happy Prime customer. We got it accidentally with some promotion and renewing ever since, I couldn't justify getting it, turns out it totally worth it because of convenience. My only complaint is inconvenience with deliveries over weekend. Quite often I need something on weekend and right now I have to order it by Wednesday night to get it (to be fair, recently they started to do some deliveries on Saturday). It's very frustrating when I recall something I need to use on the weekend on Friday and there is no way to get it on Sunday. Jeff Bezos, solve last mile and deliver 7 days a week already!
