One point that I haven't seen raised yet is that a reduction in the # of dynos required to operate a service would provide the benefit of being able to run certain addons that are priced on a per dyno basis more cheaply (e.g. NewRelic).

I've been told they're encouraging add-ons to move away from a per-dyno price. (Looked like New Relic is the only one right now).

The guys I talked to cited both the future (now present) "dyno is not a unit" problem, as well as reporting user dissatisfaction with non-flat-rate billing.
