Would you have a problem with a game where you can pay to make the ads go away, or to get more levels?

Because it seems to me that those are two very good uses of in-app purchases.

Nope, I consider that fine. In fact I think paying to make ads go away is a fantastic business model. It doesn't matter if it's a separate app or in-app purchases in my mind.
