I hope they keep it relatively ad free. Knowing Google their Home Advertiser thingie will be mostly ads, just like everything else that is Google. But I bet Amazon is merely going to introduce a method where they can get a cut out of the ads. I had to call Amazon CS over the weekend because of a item I bought that was total garbage when I received it. While I was on hold with them they played Amazon music and made sure I knew which song it was and that it was being played via Amazon music. A not so subtle ad while waiting on hold. My guess is there was no reason to put me on hold for two minutes other than to push Amazon music. Meh. Thankfully they quickly resolved the faulty product issue and refunded my money.
